Great Dane vs Rottweiler: Gentle Giant vs Powerful Guardian — When Size Meets Purpose

Stand a Great Dane next to a Rottweiler and the contrast is immediate: one breed is extraordinarily tall and elegant, the other is compact and powerfully built. The Great Dane towers at 28-32 inches tall, weighing 110-175 pounds (with some exceeding 200 pounds) in a lean, athletic frame. The Rottweiler stands 22-27 inches tall, weighing 80-135 pounds in a stocky, muscular build.​

“The Rottweiler and the Great Dane stand at opposite ends of the size spectrum” when it comes to height, but both are undeniably large, powerful dogs. Great Danes are “one of the tallest dog breeds, towering between 28 to 32 inches at the shoulder” while Rottweilers are “renowned for [their] sturdy build and imposing presence”. Think of it this way: Great Danes are basketball players—tall, lean, and graceful. Rottweilers are linebackers—compact, muscular, and explosive.​

But size differences pale beside temperament contrasts. Great Danes are “gentle giants” known for “lovable goofiness” who are “friendly and affectionate to both family and strangers”. “Despite their size, Great Danes are typically very aware of smaller dogs and will often lie down or adjust their play style to accommodate smaller companions” demonstrating remarkable gentleness. They’re “natural peacekeepers” who “seem to have an innate ability to sense tension and will often position themselves to defuse potentially problematic situations”.​

Rottweilers are powerful guardians “loved for their loyalty and affection” with “strong protective instincts” making them “excellent family guardians”. “Historically Rottweilers were bred to guard livestock so they have a strong territorial nature they’re naturally suspicious of strangers but when properly trained they can distinguish between a genuine threat” from normal situations. They’re “incredibly loving and social many develop a nurturing role within the family often showing a gentle almost parental affection toward children they’re playful patient” with their families while remaining vigilant toward threats.​​

The protection difference defines daily life: Great Danes are “friendly toward unfamiliar dogs” and “usually friendly toward strangers” making them poor guard dogs despite intimidating size. “It is an intimidating watchdog and a fair protection dog” at best. They’ll alert to disturbances with deep barks but won’t protect aggressively.​

Rottweilers are “one of the best family guard dogs due to their strong protective instincts, loyalty, and intelligence”. “When there’s a Potential Threat however they can quickly switch gears and become fiercely protected” moving from gentle family companion to formidable guardian instantly. Their “protective instincts and loyalty make them excellent family guardians. They are particularly effective in deterring burglars and intruders”.​​

For families seeking tall, elegant giants who are universally friendly and make poor guard dogs, Great Danes offer “gentle disposition” with “calm energy”. For families seeking compact, powerful guardians who bond deeply with families while remaining protective, Rottweilers provide “loyalty this breed bonds deeply with their families creating a natural drive to defend and protect”.​​

But both breeds share a devastating reality: tragically short lifespans. Great Danes live 7-10 years with “some living only 6 or 7 years, and a lucky few reaching the ripe old age of 12”. Rottweilers live 8-11 years (sometimes listed as 9-10 years). Neither lives long enough.​

Both die primarily from bloat (gastric dilatation-volvulus) and cancer. “Bloat, or gastric dilatation-volvulus (GDV), is a life-threatening condition that occurs when the stomach fills with gas and twists, cutting off the blood supply. Bloat can be fatal and requires immediate veterinary attention”. Emergency surgery costs $1,500-$7,500 and many dogs don’t survive.​

Rottweilers face additional cancer crisis: they’re “at risk for… osteosarcoma” (bone cancer) which is “particularly devastating”. Great Danes face “dilated cardiomyopathy” causing heart failure.​

Choose Great Danes if you want: extremely tall elegant dogs, universally friendly temperaments, dogs who are “gentle with smaller dogs” and natural “peacekeepers,” minimal guarding instincts, and willingness to be “couch potatoes” despite size. Accept 7-10 year lifespan.​

Choose Rottweilers if you want: compact powerful guardians, protective instincts toward family, “aloof” wariness toward strangers, natural guarding ability, and higher energy requiring “high-energy play sessions”. Accept 8-11 year lifespan.​​

Avoid both if you: cannot emotionally handle 7-11 year lifespans, cannot financially manage bloat/cancer treatment ($5,000-$20,000), cannot provide 2+ hours daily exercise, lack experience with giant or guardian breeds, or want dogs living 12-15+ years.​

Physical Differences: Height Versus Bulk

Size Specifications: Opposite Approaches to “Large”

Great Dane Dimensions:

• Height: Males 30-32 inches (minimum 30″), females 28-30 inches (minimum 28″)​
• Weight: 110-175 pounds officially, with many exceeding 200 pounds​
• Build: “Tall and lean” with “massive square-jawed” head but “elegant appearance”​

“The Great Dane reigns as one of the tallest dog breeds, towering between 28 to 32 inches at the shoulder. Their exceptional height commands attention and admiration wherever they go”. They’re built vertically—height dominates visual impression.​

Rottweiler Dimensions:

• Height: Males 24-27 inches, females 22-25 inches​
• Weight: 80-135 pounds (males typically 95-135 lbs, females 80-100 lbs)​
• Build: “Shorter but with a heavy, stocky body” and “robust mass”​

“The Rottweiler, renowned for its sturdy build and imposing presence” has “muscular” frame emphasizing power over height. They’re built horizontally—width and bulk dominate visual impression.​

The Visual Contrast

“While both are large, Great Danes can reach 200 pounds, while Rottweilers typically stay in the 100-pound range. One breed is tall and lean, while the other is shorter but with a heavy, stocky body”.​

Stand them side-by-side: Great Danes are 4-8 inches taller but similar or only slightly heavier weight. The height difference is dramatic—Great Danes tower over Rottweilers. But Rottweilers’ compact muscle mass creates similar overall heft despite shorter stature.​

A 150-pound Great Dane at 32 inches tall appears lean and graceful. A 120-pound Rottweiler at 25 inches tall appears massively muscular and broad. Different approaches to “large dog”.​

Build Purpose: Elegance Versus Power

Great Dane Build: Bred as royal hunting dogs chasing “bear, boar, and deer at princely courts” requiring speed and athleticism. Their lean, tall builds allowed sustained running and jumping during hunts. Modern Great Danes retain this elegant athleticism despite no longer hunting.​

“Naturally Gentle Disposition Great Danes seem to understand their size and typically adjust their behavior accordingly” showing body awareness. They’re “not typically high-energy dogs” despite athletic builds.​

Rottweiler Build: Bred as “drover dogs” driving and guarding cattle requiring power, endurance, and intimidating presence. “These courageous canines… played a crucial role in driving and guarding cattle” and pulling “cart-pulling” loads. Their compact, muscular builds provided strength and stability for physical work.​

“They’re strong, imposing dogs that can weigh upwards of 100 pounds” with builds emphasizing power. Modern Rottweilers retain this powerful build even without working cattle.​

Coat and Colors

Great Dane Coat: “Short coat, but it is smooth and sleek in texture. Their coat is low-maintenance and easy to care for”. The coat is “fine” and lies flat.​

Colors: “Great Danes come in a variety of coat colors, including black, white, fawn, blue, harlequin, and mantle” plus brindle, merle, chocolate, and others. The iconic harlequin (white with irregular black patches) is stunning and recognizable.​

Rottweiler Coat: “Short, dense, and straight coats. Their coat sheds a moderate amount and is relatively easy to groom”. “Low to moderate” grooming needs.​

Colors: Rottweilers have “distinctive coat color pattern. Their primary coat color is black, with clearly defined rust, tan, or mahogany-colored markings on the cheeks, legs, chest, and eyebrows”. This coloring is iconic and consistent across the breed.​

Movement and Athleticism

Great Dane Movement: Surprisingly graceful despite massive size. “Great Danes are typically very aware of smaller dogs and will often lie down or adjust their play style to accommodate smaller companions. This sensitivity makes them wonderful playmates for dogs of all sizes”.​

They can run, play, and move athletically but tire relatively quickly. “Great Danes will serve as excellent ambassadors for large breed dogs… Their gentle nature and impressive presence often help dispel misconceptions about large dogs being aggressive or uncontrollable”.​

Rottweiler Movement: Powerful, explosive, and surprisingly quick for their bulk. They’re “active and agile dogs requiring regular physical activity to maintain health”. “They also require plentiful mental stimulation”.​

Rottweilers are more athletic and energetic than Great Danes despite similar weight. “They are active breeds, but Great Danes are a little more willing to be couch potatoes than Rottweilers”.​

Temperament and Personality: Friendly Giant Versus Loyal Guardian

Great Dane Temperament: The Gentle Giant

“While ‘gentle giant’ may be an overused phrase, it aptly describes the Great Dane. Though large, it is generally friendly and affectionate to both family and strangers”. This isn’t marketing—it’s documented reality.​

Key Descriptors:

• “Gentle” and “warm”​
• “Friendly and affectionate” to everyone​
• “Lovable goofiness”​
• “Calm” and “easygoing”​
• “Patient” with children and other pets​

“Great Danes are large, friendly, and courageous dogs” but their courage doesn’t translate to aggression. They’re “gentle giants” who “tend to be reserved pets who are quite content to play lap dog on the couch with their family members (even if they don’t really fit.)”.​

Social Nature: “Great Danes are usually friendly toward unfamiliar dogs, and they get along well with housemates”. They’re “exceptionally social. They have high energy levels and a need for mental stimulation. They also thrive on companionship and enjoy being around people. This breed may suffer from separation anxiety”.​

“Great Danes are gentle, calm, and social, with a gentle disposition, social awareness, and act as peacekeepers, making them good” companions. “Many Great Danes seem to have an innate ability to sense tension and will often position themselves to defuse potentially problematic situations. This natural peacemaking ability makes them valuable community members”.​

With Children: “Even though Great Danes are giant dogs, they are incredibly gentle and caring with babies. Their strength combined with their affection makes them great family dogs”. “Great Danes are generally very calm around kids unless it feels pushed beyond its limits”.​

“They have a relatively low energy level and a high tolerance for young kids, even rambunctious ones”. They’re “patient and dependable”. However, “Great Danes have this habit of jumping when they are over-excited. This can be risky for children who are below six years old, as these dogs can easily knock them off”.​

Guard Dog Reality: “Great Danes also make great guard dogs, both because of their size and because they’re very loyal to their families. Your Great Dane will probably act as a watchdog and alert you of any activity they deem suspicious”. However, “it is an intimidating watchdog and a fair protection dog” at best.​

They’re not protective or aggressive. Their friendliness toward strangers prevents effective guarding. “The Great Dane does not bark without reason” but barking is extent of protection.​

The Goofiness Factor: “Great Danes are known for their lovable goofiness”. They’re playful, silly, and entertaining despite massive size. “They may be distractable during training, but they aim to please and generally respond well to training sessions”.​

Rottweiler Temperament: The Loyal Protector

“Rottweilers are widely regarded as one of the best family guard dogs due to their strong protective instincts, loyalty, and intelligence”. This combination creates dogs who are “incredibly loving and social” with families while remaining “fiercely protected” when threats appear.​​

Key Descriptors:

• “Loyal, confidence, and protective nature”​
• “Affectionate and devoted to their families”​
• “Gentle almost parental affection toward children”​
• “Aloof” and “distrust strangers”​
• “Strong territorial nature”​

“The Rottweiler has achieved a reputation as an aggressive and dangerous dog, but this couldn’t be further from the truth for the people that love them. Rottweilers are incredibly loyal and protective dogs. They are often considered one of the best breeds to have with children because of their gentleness and loyalty”.​

The Dual Nature: “When there’s a Potential Threat however they can quickly switch gears and become fiercely protected”. This switch—from gentle family companion to formidable guardian—defines Rottweilers.​

“It’s not just about their size their natural instinct to protect their family is deeply ingrained historically Rottweilers were bred to guard livestock so they have a strong territorial nature they’re naturally suspicious of strangers but when properly trained they can distinguish between a genuine threat” from normal situations.​

With Family: “Despite their tough exterior they’re affectionate patient and gentle with children making them excellent companions in a family setting”. “Rottweilers can be trained to accompany and protect individuals, offering both companionship and safety”.​​

“They’re not only guarding your physical space but will instinctively sense if something feels off this Instinct combined with their loyalty and intelligence is what makes them such effective family guard dogs they don’t just rely on their physical strength they’re also mentally” alert.​

Protection Instinct: “Another key trait of the Rottweiler is its protective instinct when properly socialized and trained a Rottweiler will go to Great Lengths to protect its family”. “Their protective instincts and loyalty make them excellent family guardians. They are particularly effective in deterring burglars and intruders”.​​

The Guardian Role: “Rottweilers are naturally protective, with a muscular build and confident attitude. They’re quick to assess threats and act” decisively. “They are at risk” but “maintaining a healthy body weight is vital for joint health, while routine veterinary checkups will help catch other health conditions early”.​

Social Nature: “Rottweilers are social dogs that have moderate energy levels and a need for mental stimulation. They benefit from regular interaction with other people and animals, in addition to love and affection from their owners”. However, “they tend to be aloof and distrust strangers, especially if they feel like their people are at risk”.​

Energy Levels: Moderate Versus High

Great Dane Energy: “Danes have a fairly low energy level, and, while playful, they are ready to quit and do something else after just a little while”. They’re “not typically high-energy dogs. They appreciate moderate exercise and social interaction, making them perfect for the relaxed yet engaging atmosphere” of family life.​

“They are active breeds, but Great Danes are a little more willing to be couch potatoes than Rottweilers”. After moderate exercise, they’re content lounging.​

Exercise needs: “1+ hours a day” minimum but can be moderate intensity. “2+ hours a day” listed in some sources but this may include lounging time with family.​

Rottweiler Energy: “Rottweilers are active and agile dogs requiring regular physical activity to maintain health. They also require plentiful mental stimulation”. “This breed usually doesn’t enjoy being a couch potato, so be prepared for high-energy play sessions”.​

Exercise needs: “2+ hours a day” of active engagement. “Engaging in daily walks, play sessions, and interactive training exercises or toys can help channel their energy positively and prevent boredom-related behaviors”.​

“They require a lot of exercise, so they are best suited for active homes with plenty of outside time”. Rottweilers need structured activity—not just yard time.​

Training and Intelligence

Great Dane Training: “Great Danes are generally considered easy to train. They can be somewhat stubborn, and they don’t tend to react well to harsh training methods”. “When you rely on tried-and-true obedience training methods that use positive reinforcement, you’ll see good results”.​

“The breed is easy to train but is not a quick responder”. They understand commands but execute slowly. “While Great Danes are eager to please, they can still pose some challenges with training… They may be distractable during training, but they aim to please and generally respond well to training sessions”.​

Training Challenges: “One issue that people may need to consider is how quickly these dogs grow. Have you ever tried to train a wild puppy weighing 50 pounds?”. Managing giant puppies requires creativity.​

“Trainability: Eager to please, sociable, people-oriented”. They want to please but get distracted easily.​

Rottweiler Training: “Due to the large size and strength of the Rottweiler, coupled with its protectiveness, it’s essential to provide appropriate socialization and training. Training should start at a young age”.​

“While they are intelligent dogs, they are wise enough sometimes to try to outsmart you. You must have a well-planned training regimen and high-value rewards to maintain the attention of a Rottweiler. They tend to be people pleasers, and that helps significantly with training”.​

“Trainability: Intelligent, stubborn, confident”. They’re highly intelligent but independent thinkers. “The primary challenge with training Rottweilers is their high intelligence and tendency to try to outsmart you”.​

Socialization: Critical for Both Breeds

Both breeds require extensive early socialization.​

Great Danes: “Appropriate socialization at a young age is vital to ensure the best temperament traits are brought forward. Without proper socialization, Great Danes can become jumpy and nervous”. They’re naturally friendly—socialization builds confidence.​

Rottweilers: “Early socialization plays a crucial role in shaping a well-mannered and confident Rottweiler”. They’re naturally suspicious of strangers—socialization teaches appropriate discrimination between threats and normal situations.​​

“Their natural protectiveness makes early socialization vital to expose the Rottweiler to various people, animals, places, and experiences. By doing so, owners can help instill a well-mannered and confident demeanor, minimizing potential behavioral issues and encouraging friendliness”.​

Lifespan and Health: The Heartbreak Reality

The Numbers: Too Short for Both

Great Dane Lifespan: 7-10 years. “Great Danes live between 8-to-10 years, with some living only 6 or 7 years, and a lucky few reaching the ripe old age of 12”.​

“Great Danes typically live around 7 to 10 years”. “Lifespan: 8–10 years” is most common listing. The reality: many die before age 10.​

Rottweiler Lifespan: 8-11 years, often listed as 9-10 years. “Rottweilers live between 9 to 10 years”. “Lifespan: 8–10 years”.​

The Comparison: “The Rottweiler’s breeding and body type grants it a slightly longer life expectancy on average. At the same time, the Great Dane’s towering size impacts its lifespan, leading to a somewhat shorter average”. Rottweilers live 1-2 years longer on average.​

But neither lives long enough. Both are considered senior dogs by age 6-7.​

Why Giant/Large Breeds Die Young

“Conversely, the Great Dane’s colossal size places some strain on its body, impacting its life expectancy. These gentle giants tend to have a shorter lifespan, generally ranging from 7 to 10 years. While some Great Danes may live beyond 10 years with proper care, their size, and specific health challenges may contribute to a slightly shorter life span compared to other breeds”.​

Larger bodies wear out faster: hearts pump harder, joints bear more weight, organs work harder maintaining massive frames.​

Bloat: The Shared Killer

Both breeds are highly susceptible to bloat (gastric dilatation-volvulus or GDV).​

What is Bloat: “Bloat, or gastric dilatation-volvulus (GDV), is a life-threatening condition that occurs when the stomach fills with gas and twists, cutting off the blood supply. Bloat can be fatal and requires immediate veterinary attention”.​

“The breed is particularly susceptible to bloat, a dangerous and often fatal condition that results in the stomach twisting and cutting off blood supply”. For Rottweilers: “Gastric Dilatation-Volvulus (GDV)” is major health concern.​

Emergency Treatment: Surgery costs $1,500-$7,500. “Dogs that suffer from bloat once often get it a second time, and your veterinarian may recommend a tacking procedure to try and minimize future risk”.​

Preventative Gastropexy: Many owners elect prophylactic stomach tacking surgery ($1,400-$1,600) during spay/neuter preventing the twist. Strongly recommended for both breeds.​

Great Dane Specific Health Issues

Dilated Cardiomyopathy (DCM): Heart disease where “the heart’s ability to pump blood” fails. Progressive and often fatal.​

Hip Dysplasia: “Great Danes are prone to hip dysplasia, leading to joint pain and mobility issues”.​

Bone/Joint Issues: “Given their massive size, Great Danes may experience joint and bone issues when compared to the average dog. Joint and bone issues can include osteochondrosis (a disorder affecting the development of bones and cartilage) and arthritis”.​

Rapid Puppy Growth: “Great Dane puppies grow so quickly that they can develop issues with their joints and bones, so proper nutrition and exercise at a young age are necessary”. Feed large-breed puppy formula slowing growth rate.​

Other Issues: Cancer (osteosarcoma), Mitral valve disease, Patent ductus arteriosus, Tricuspid valve dysplasia, Subartotic Stenosis, Persistent right aortic arch.​

Rottweiler Specific Health Issues

Hip and Elbow Dysplasia: “Rottweilers are prone to hip dysplasia, elbow dysplasia”. “Hip Dysplasia is a genetic condition where the hip joint doesn’t fit properly into the hip socket, leading to pain and mobility issues. Similar to hip dysplasia, elbow dysplasia is a condition that affects the elbow joint and can cause lameness and discomfort”.​

Cancer – Osteosarcoma: “Rottweilers are at higher risk for certain types of cancers, such as osteosarcoma (bone cancer) and lymphoma”. Osteosarcoma is particularly devastating—aggressive bone cancer requiring amputation and chemotherapy.​

Heart Problems: “Rottweilers may be prone to certain heart conditions like dilated cardiomyopathy, which affects the heart’s ability to pump blood effectively”. Aortic stenosis is another concern.​

Other Issues: “Injuries to their cranial cruciate ligament, eyelid problems”. Hypothyroidism, allergies. “Obesity” is major concern—”Maintaining a healthy body weight is vital for joint health”.​

Health Screening Requirements

For Great Danes:

• Cardiac evaluations (echocardiograms for DCM)
• Hip evaluations (OFA/PennHIP)
• Eye examinations
• Thyroid testing
• Consider preventative gastropexy

​

For Rottweilers:

• Hip and elbow evaluations (OFA/PennHIP) – mandatory
• Cardiac evaluations
• Eye examinations
• Cancer screening protocols
• Consider preventative gastropexy

​

Breeder Responsibility: “Proper breeding practices through responsible breeders are necessary to prevent these issues in future generations”. “Most of them are being perpetuated by irresponsible breeders”. Choose breeders providing health clearances.​

The Emotional Reality

“Both breeds require regular veterinary check-ups, a balanced diet, and adequate exercise to maintain their well-being”. However, even with excellent care, most Great Danes die by age 10 and most Rottweilers by age 11.​

Prospective owners must accept: you will likely have less than a decade with your dog. “Great Danes live between 8-to-10 years, with some living only 6 or 7 years”. This isn’t worst-case scenario—it’s common reality.​

That decade passes with terrifying speed. Puppyhood lasts 18-24 months. Prime adult years are 2-6. Senior years begin at 6-7. Elderly/geriatric begins at 8-9. Death typically occurs before age 11.​

Real Owner Experiences

Marcus, 48, Great Dane Owner (Oregon) – Three Great Danes Over 15 Years

“I’ve owned three Great Danes over 15 years. Every one died before age 10. I keep choosing them because their gentle, goofy personalities are worth the heartbreak—but barely.

My first Dane, Thor, died at age 8 from bloat. Emergency surgery cost $5,800. He survived surgery but developed complications and died 48 hours later. I had preventative gastropexy done on my next two Danes—learned that lesson.

My second Dane, Luna, lived to 9 years. She had hip dysplasia requiring surgery at age 6 ($4,200) and developed dilated cardiomyopathy at age 8. We managed with medications for 11 months before her heart failed. Total DCM costs: $9,000.

My current Dane, Zeus, is 7 years old. I’m hyper-aware that time is limited. Every day is precious because I know I probably have 1-3 years left with him maximum.

The lifespan reality is devastating. People who’ve never owned giant breeds don’t understand—you lose your dog when they should have years remaining. My kids (now teenagers) have grown up experiencing repeated grief from short-lived dogs.

But Great Danes are extraordinary. Zeus is gentle with our cats, patient with neighborhood kids, and thinks he’s a lap dog despite weighing 165 pounds. He alerts when strangers approach but greets them warmly once I indicate they’re welcome. He’s useless as guard dog but perfect as gentle companion.

For families wanting extremely tall, universally friendly giants—Great Danes are amazing. But accept the 7-10 year reality emotionally and financially before committing.”

Rebecca, 52, Rottweiler Owner (Texas) – Two Rottweilers Over 20 Years

“I’ve owned two Rottweilers over 20 years. Both died from cancer before age 11. They were devoted family protectors but the lifespan/health issues are heartbreaking.

My first Rottweiler, Bear, was perfect family guardian. Gentle and playful with my kids, protective toward strangers, naturally discriminating between threats and normal situations with minimal training. At age 9, he developed osteosarcoma in his rear leg. We amputated ($6,500) and did chemotherapy ($4,800). He lived 14 months post-diagnosis.

My current Rottweiler, Titan, is 8 years old and healthy so far. But I’m constantly monitoring for cancer signs, limping, or behavior changes. Every vet visit includes cancer screening discussions. The 45% cancer mortality rate for Rottweilers is terrifying.

The protection instinct is remarkable. Titan lies between my family and strangers visiting our home. When delivery drivers approach, he positions himself protectively but doesn’t bark excessively or act aggressively. Once I welcome visitors, he relaxes but remains watchful.

He’s incredibly affectionate with family—follows me everywhere, leans against me constantly, sleeps next to my bed. The bond is intense. He’s gentle with my grandchildren but I supervise because 120 pounds of protective dog requires management.

Training was essential. Rottweilers are intelligent and strong—without training, they’re liabilities. We did professional training focusing on protection instinct management, obedience, and socialization. Cost: $2,500 but absolutely necessary.

For families wanting powerful guardians bonding deeply with families—Rottweilers are excellent. But prepare for 8-11 year lifespans ending with expensive cancer treatment and devastating grief.”

Daniel, 35, Former Great Dane Owner, Now Has Labrador (California)

“I owned a Great Dane for 8 years. I will never own another giant breed. The grief destroyed me.

Apollo was perfect—friendly, gentle, goofy. My kids (then ages 3 and 6) adored him. He was their best friend, their playmate, their protector.

At age 7, he developed bloat despite having preventative gastropexy. The surgery prevented the twist but his stomach still dilated—emergency vet, $3,900. He survived.

Six months later, he developed dilated cardiomyopathy. Medications managed it for 11 months. He died at age 8 years, 5 months. Total heart disease costs: $11,000. Pet insurance covered $6,500.

My daughter (then 11) sobbed for weeks. My son (then 14) became withdrawn. Losing Apollo traumatized our family. The dog was supposed to grow up with my kids—instead, he died when they were still young.

After Apollo, I researched lifespans. The 7-10 year reality for giant breeds versus 10-14 years for medium breeds matters enormously. We now have a Labrador Retriever. She’s 4 years old and will likely live to 12-14. My kids will graduate high school before she dies—not middle school.

I loved Apollo. Great Danes are wonderful dogs. But the short lifespan creates repeated grief. For families with children—seriously consider medium breeds living longer. Your kids will thank you.”

Frequently Asked Questions

1. Which breed is taller?

Great Danes are dramatically taller: 28-32 inches versus Rottweilers’ 22-27 inches. Great Danes are 4-8 inches taller making them “one of the tallest dog breeds”. Rottweilers are “shorter but with a heavy, stocky body”.​

2. Which breed weighs more?

Similar weights despite height difference: Great Danes weigh 110-175+ pounds, Rottweilers weigh 80-135 pounds. Many Great Danes exceed 200 pounds while Rottweilers typically stay under 135 pounds. However, a 120-pound Rottweiler appears more massively built than a 150-pound Great Dane due to compact musculature versus lean athleticism.​

3. Which breed lives longer?

Rottweilers live slightly longer: 8-11 years (often 9-10 years) versus Great Danes’ 7-10 years. “The Rottweiler’s breeding and body type grants it a slightly longer life expectancy on average” by 1-2 years. However, neither lives long enough.​

4. Which breed is better with children?

Both are excellent when properly socialized. Great Danes are “incredibly gentle and caring with babies” and “patient”. Rottweilers are “often considered one of the best breeds to have with children because of their gentleness and loyalty”. Supervision required for both due to size. Great Danes may jump when excited knocking over children; Rottweilers’ protective instincts require training.​​

5. Which breed makes a better guard dog?

Rottweilers are dramatically better. They’re “one of the best family guard dogs due to their strong protective instincts, loyalty, and intelligence”. “Their protective instincts and loyalty make them excellent family guardians. They are particularly effective in deterring burglars and intruders”.​​

Great Danes are “intimidating watchdog[s] and fair protection dog[s]” at best due to friendly temperaments. They’re “usually friendly toward strangers” preventing effective guarding.​

6. Do both breeds have bloat risk?

Yes, both are highly susceptible. “Bloat, or gastric dilatation-volvulus (GDV), is a life-threatening condition that occurs when the stomach fills with gas and twists, cutting off the blood supply”. “The breed is particularly susceptible to bloat” for Great Danes. Rottweilers are similarly at risk. Emergency surgery costs $1,500-$7,500. Preventative gastropexy ($1,400-$1,600) strongly recommended for both breeds.​

7. Which breed is more energetic?

Rottweilers are more energetic. They’re “active and agile dogs requiring regular physical activity” and “high-energy play sessions”. They need 2+ hours daily active exercise. Great Danes “have a fairly low energy level” and are “a little more willing to be couch potatoes”. They need 1-2 hours moderate exercise.​

8. Which breed is easier to train?

Great Danes are easier for beginners. They’re “eager to please, sociable, people-oriented” though “can be somewhat stubborn”. Rottweilers are “intelligent, stubborn, confident” who “try to outsmart you”. “The primary challenge with training Rottweilers is their high intelligence and tendency to try to outsmart you”. Both respond well to positive reinforcement.​

9. Do both breeds require professional training?

Rottweilers absolutely need professional training due to protective instincts and strength. “Due to the large size and strength of the Rottweiler, coupled with its protectiveness, it’s essential to provide appropriate socialization and training”. Great Danes benefit from training but less critically. Training helps manage size but isn’t mandatory like Rottweilers.​​

10. Which breed is more affectionate?

Both are highly affectionate with families. Rottweilers “bond deeply with their families” and are “affectionate patient and gentle with children”. Great Danes are “friendly and affectionate to both family and strangers” and “content to play lap dog on the couch”. Difference: Great Danes are friendly to everyone; Rottweilers reserve affection for family while remaining aloof to strangers.​​

11. Can either breed live in apartments?

Not recommended. Both need space for their size. Great Danes need “large area in which to stretch out and sleep”. Rottweilers need “plenty of outside time” for exercise. Both require yards and houses accommodating giant/large breed sizes.​

12. How much do these breeds eat daily?

Great Danes: 6-8 cups daily ($100-$165 monthly, $1,200-$2,000 annually) for 110-175 pound dogs

Rottweilers: 4-6 cups daily ($75-$120 monthly, $900-$1,400 annually) for 80-135 pound dogs

Great Danes eat significantly more due to larger size.​

13. Do both breeds drool?

Minimal for both breeds. Neither has loose jowls creating excessive drool. Expect normal doggy drool after drinking water but not constant slobber like Mastiffs.​

14. Which breed sheds more?

Similar shedding. Both have short coats shedding moderately year-round. “Rottweilers have short, dense, and straight coats. Their coat sheds a moderate amount and is relatively easy to groom”. Great Danes have “low-maintenance” coats. Grooming needs: “Low” for Great Danes, “Low to moderate” for Rottweilers.​

15. Are Great Danes really “gentle giants”?

Yes, genuinely. “While ‘gentle giant’ may be an overused phrase, it aptly describes the Great Dane”. “Great Danes seem to understand their size and typically adjust their behavior accordingly”. They’re “gentle with smaller dogs” and act as “natural peacekeepers”. This isn’t marketing—it’s documented temperament.​

16. Are Rottweilers really aggressive?

No—this is myth. “The Rottweiler has achieved a reputation as an aggressive and dangerous dog, but this couldn’t be further from the truth for the people that love them”. They’re “incredibly loyal and protective dogs” who are “gentle almost parental” with children. However, they’re “naturally suspicious of strangers” requiring socialization teaching threat discrimination. Protective ≠ aggressive.​​

17. Can either breed be left alone during workdays?

Great Danes struggle more. They “may suffer from separation anxiety”. “Regular social interaction and spending quality time with their owners are essential for their emotional well-being”. Rottweilers tolerate alone time slightly better but need midday visits for 8+ hour absences. Neither is ideal for people working full-time without dog care.​

18. Which breed is better for first-time dog owners?

Great Danes are slightly better due to friendlier temperaments and lower guarding instincts. However, neither giant/guardian breed is truly ideal for first-time owners. Both require: experience managing large/powerful dogs, understanding health issues, financial capacity, and commitment to training/socialization. First-time owners should seriously consider medium breeds.​

19. What’s the “Weiler Dane” (Great Dane Rottweiler mix)?

“Known as a Weiler Dane, this breed of dog combines the height of a Great Dane and the muscular bulk of the Rottweiler”. They’re “intimidating due to their physical size but they are a very sweet breed” resembling Rottweilers in color with “broad chest, a long tail, and ears that are long and floppy”. Mixes lack predictability of purebreds.​

20. Do these breeds get along with other dogs/pets?

Great Danes are better with other pets. They’re “usually friendly toward unfamiliar dogs, and they get along well with housemates”. They’re “gentle with smaller dogs”. However, they “can have a jealous streak” requiring socialization.​

Rottweilers can coexist but require management. “Early socialization vital to expose the Rottweiler to various people, animals, places”. Protective instincts may create issues with strange dogs.​

21. How much does emergency bloat surgery cost?

$1,500-$7,500 for emergency treatment. “Dogs that suffer from bloat once often get it a second time, and your veterinarian may recommend a tacking procedure to try and minimize future risk”. Many dogs don’t survive even with surgery. Preventative gastropexy before bloat occurs costs $1,400-$1,600 and is strongly recommended.​

22. At what age are these breeds considered senior?

Age 6-7 years for both breeds. Giant/large breeds age faster than medium breeds. By age 7, they’re elderly. By age 8-9, they’re geriatric. This accelerated aging explains short lifespans.​

23. Can I reduce bloat risk through feeding management?

Yes, somewhat. Feed multiple small meals daily instead of one large meal, use slow-feed bowls, avoid exercise immediately after eating, and don’t allow rapid eating. However, preventative gastropexy is most effective prevention. “Talk to your veterinarian about the symptoms of bloat and how it can be avoided”.​

24. Which breed is better in hot climates?

Neither is ideal but Great Danes tolerate heat slightly better than Rottweilers. Both need air conditioning, limited summer activity, and heat monitoring. Rottweilers’ black coats absorb heat making them particularly susceptible. For hot climates, choose different breeds.​

25. Do Great Danes really try to be lap dogs?

Yes, genuinely. They’re “content to play lap dog on the couch with their family members (even if they don’t really fit.)”. This isn’t exaggeration—150+ pound Great Danes genuinely believe they’re lap dogs and will attempt to sit on owners’ laps.​

26. How do I find responsible breeders for these breeds?

Verify breeders provide:

• Hip/elbow evaluations (OFA/PennHIP scores)
• Cardiac evaluations (especially Great Danes for DCM)
• Multi-generation pedigrees showing longevity
• Health guarantees
• Lifetime breeder support
• Dogs competing in shows or working events

Visit facilities, meet adult dogs, observe temperaments, demand health documentation. “Proper breeding practices through responsible breeders are necessary to prevent these issues in future generations”.​

27. Should I get preventative gastropexy for my dog?

Yes, strongly recommended for both breeds. Cost is $1,400-$1,600—far less than emergency bloat surgery ($1,500-$7,500). “Many owners elect to have the stomach surgically attached to the abdominal wall to prevent this”. Can be done during spay/neuter surgery. Prevents twist but not dilation—still need emergency care if bloating occurs.​

28. Which breed is more “stubborn”?

Rottweilers are more stubborn/independent. They’re “intelligent, stubborn, confident” who “try to outsmart you”. Great Danes “can be somewhat stubborn” but are generally more eager to please. Neither is as biddable as Golden Retrievers.​

29. Can either breed do dog sports?

Both can participate moderately. Great Danes can do obedience, rally, and some agility though size makes obstacles challenging. Rottweilers excel in protection sports, obedience, tracking, and cart pulling. Neither is ideal for high-intensity agility.​

30. Which breed bonds more strongly with families?

Rottweilers bond more intensely. “Rottweilers this breed bonds deeply with their families creating a natural drive to defend and protect”. Great Danes bond affectionately but maintain friendly relationships with everyone. Difference: Rottweilers’ bonds are exclusive to family; Great Danes’ bonds extend to strangers.​​

31. Do either breed “turn on” their owners?

No—this is myth. Properly bred, socialized, and trained dogs don’t “turn on” owners. “The Rottweiler has achieved a reputation as an aggressive and dangerous dog, but this couldn’t be further from the truth”. Incidents result from: poor breeding, lack of socialization, abusive training, or medical issues—not breed temperament. Both breeds are loyal and devoted.​​

32. How much space do these breeds need?

Both need large homes and yards. Great Danes need “large area in which to stretch out and sleep” plus space to move without knocking things over. Rottweilers need “plenty of outside time” for exercise. Both require: large vehicles for transport, wide doorways/hallways, spacious bedding areas, and yards for exercise.​

33. Are these breeds good for seniors or retirees?

Generally not recommended. Both breeds’ size and strength make them difficult for elderly owners to manage. Great Danes are calmer but size is challenging. Rottweilers need extensive exercise and training. Active, strong retirees can succeed with Great Danes; most seniors should choose smaller breeds.​

34. Which breed is more vocal/barks more?

Both are relatively quiet. Great Danes “do not bark without reason”. Rottweilers bark to alert but aren’t nuisance barkers. Both have deep, intimidating barks. Neither is excessively vocal compared to breeds like Beagles or Huskies.​

35. Can either breed be service dogs?

Both can serve as service dogs in specific roles. Rottweilers “can be trained to accompany and protect individuals, offering both companionship and safety”. Great Danes can serve as mobility assistance dogs due to size and gentleness. However, neither is ideal for public access service work—Great Danes due to size management in public, Rottweilers due to protective instincts.​

36. Do males or females make better pets?

Sex differences are minimal compared to individual temperament. Males of both breeds are larger and heavier. Some report males more affectionate, females more independent, but individual variation exceeds sex patterns. Choose based on individual puppy temperament, health testing, and breeder recommendations—not sex stereotypes.​

37. Why are these breeds surrendered to rescue?

Common surrender reasons:

• Underestimating size/strength (especially Great Danes)
• Cannot afford veterinary costs (bloat, cancer)
• Cannot handle short lifespans emotionally
• Rottweiler protective instincts without training
• Unexpected health issues
• Lifestyle changes
• Great Danes’ separation anxiety

​

Many are surrendered by families who researched appearance but not reality.​

38. What’s the most important factor choosing between these breeds?

Protection needs versus friendliness. If you want natural guardians who “distinguish between genuine threats,” choose Rottweilers. If you want universally friendly dogs who are “gentle giants” greeting everyone warmly, choose Great Danes.​​

Secondary consideration: Energy levels. Rottweilers need 2+ hours daily active exercise. Great Danes are “couch potatoes” after 1-2 hours moderate activity.​

Tertiary consideration: Lifespan preparation. Both die tragically young—accept 7-11 years emotionally and financially.​

39. Can I own these breeds if I work full-time?

Challenging but possible with support. Solutions:​

• Dog walkers for midday visits
• Doggy daycare 2-3 days weekly
• Working from home partial days
• Staggered work schedules with partner

Both breeds need companionship and exercise. Great Danes suffer separation anxiety. Rottweilers need structured activity. Neither tolerates 10+ hour daily isolation well.​

40. What’s the biggest mistake people make with these breeds?

Acquiring for appearance without researching reality. People see: tall elegant Great Danes or powerful Rottweilers and assume they’re like Golden Retrievers. They underestimate: 7-11 year lifespans, $5,000-$20,000 health crises, bloat emergencies, training requirements (especially Rottweilers), exercise needs, and space requirements.​​

For Great Danes: Underestimating separation anxiety, size management challenges, and 7-10 year lifespan.​

For Rottweilers: Underestimating protective instinct management, training requirements, and exercise needs.​​

Both require informed, committed ownership—not impulse decisions.​

Final Perspective: Gentle Giant Versus Powerful Guardian

Great Danes and Rottweilers represent different philosophies of large dog ownership. Great Danes are extremely tall, elegant “gentle giants” who are “friendly and affectionate to both family and strangers” making them poor guard dogs but excellent gentle companions. Rottweilers are compact, powerful guardians who are “one of the best family guard dogs due to their strong protective instincts, loyalty, and intelligence”.​​

For families seeking tall, universally friendly giants who are “natural peacekeepers” and “gentle with smaller dogs,” Great Danes offer unique companionship. For families seeking protective guardians who “bond deeply with their families” while remaining “aloof toward strangers,” Rottweilers provide devoted protection.​​

But both breeds share devastating realities requiring brutal honesty:​

Tragically Short Lifespans: Great Danes live 7-10 years, Rottweilers 8-11 years. “Great Danes live between 8-to-10 years, with some living only 6 or 7 years”. Neither lives long enough. You’ll likely have less than a decade with your dog.​

Bloat Crisis: Both are highly susceptible to “gastric dilatation-volvulus (GDV), a life-threatening condition” requiring emergency surgery costing $1,500-$7,500. Many dogs die despite surgery. Preventative gastropexy ($1,400-$1,600) strongly recommended.​

Cancer Devastation: Rottweilers face “higher risk for certain types of cancers, such as osteosarcoma (bone cancer)”. Great Danes develop cancer frequently. Treatment costs $5,000-$20,000 with limited success.​

Financial Reality: Expect $25,000-$47,000 over 7-11 years including preventative care and averaged emergency costs. Annual costs: $2,300-$4,700 not including emergencies.​

Making the Honest Choice

Before acquiring either breed, answer truthfully:

1. Can I emotionally handle 7-11 year lifespan?​
2. Can I financially commit $25,000-$47,000 over that decade?​
3. Can I manage bloat emergency preparedness?​
4. Can I provide 1-2+ hours daily exercise for years?​
5. Do I have space for giant/large breed?​
6. (For Rottweilers) Can I manage protective instincts through training?​​
7. (For Great Danes) Can I manage separation anxiety?​
8. Can I accept inevitable premature loss?​

If you answered “no” to any question, reconsider.​

For Those Who Proceed

If you answer “yes” understanding realities, both breeds offer extraordinary experiences. Great Danes’ “gentle disposition” and “lovable goofiness” create unique companionship. Rottweilers’ “loyalty” and “strong protective instincts” provide devoted guardianship.​​

Choose Great Danes for: extremely tall elegant dogs, universal friendliness, “natural peacekeeper” temperaments, moderate energy, and gentle companionship.​

Choose Rottweilers for: compact powerful guardians, protective instincts, family devotion, high energy, and natural guarding ability.​​

Research beyond photos. Visit breeders providing health clearances. Meet adult dogs whose temperaments are evident. Talk to owners who’ve experienced 7-11 year lifespans—their stories reveal realities marketing hides.​

The Bottom Line

The tragedy of loving Great Danes and Rottweilers isn’t that they die—all dogs do. The tragedy is they die when they should have years remaining, when families aren’t ready, when bonds are strongest. “Great Danes live between 8-to-10 years, with some living only 6 or 7 years, and a lucky few reaching the ripe old age of 12”. Rottweilers live 8-11 years with similar premature endings.​

But for those who choose this journey understanding the destination, the years spent are transformative. Every day matters because days are countable. Every moment is precious because moments are finite.​​

Welcome to large/giant breed ownership. Whether you choose the elegant Great Dane or the powerful Rottweiler, you’re gaining devoted companions whose size matches their hearts. Just make sure you’re emotionally and financially prepared for journeys lasting 7-11 years—not the 12-15 you wish you had.

The love is profound. The loyalty is absolute. The grief is inevitable. Choose wisely, love deeply, and treasure every single day of your decade together. It will never be enough—but it will be worth it.
