Great Dane: Complete Guide to Temperament, Care, and Costs

The Great Dane is the gentle giant of the dog world. Standing taller than most other breeds and weighing well over 100 pounds, the Great Dane nonetheless possesses one of the sweetest, most affectionate temperaments you will find. Often called the “Apollo of dogs,” this majestic breed combines imposing physical presence with a surprisingly gentle and friendly disposition. This guide covers everything you need to know about sharing your life with one of these magnificent dogs.

Overview

The Great Dane’s origins are German, not Danish, despite the name. The breed was developed in Germany from mastiff-type dogs crossed with Greyhounds to create a powerful yet athletic dog for hunting wild boar. The German nobility prized these dogs as estate guardians and hunting companions, and the breed gradually transitioned from working dog to companion as the need for boar hunting declined.

Great Danes belong to the AKC Working Group. Males stand a minimum of 30 inches at the shoulder (many reach 32 inches or more) and weigh 140 to 175 pounds. Females stand a minimum of 28 inches and weigh 110 to 140 pounds. Accepted colors include fawn, brindle, blue, black, harlequin (white with irregular black patches), and mantle (black and white with a specific pattern). The AKC recognized the breed in 1887.

The breed holds the record for the tallest dog ever recorded — a Great Dane that measured over 44 inches at the shoulder. Despite their enormous size, Great Danes are remarkably elegant and athletic, moving with a smooth, powerful stride that belies their bulk.

Temperament and Personality

Great Danes are gentle, affectionate, and friendly dogs that seem blissfully unaware of their enormous size. They are famous for trying to be lap dogs, attempting to climb onto furniture and their owner’s laps with endearing clumsiness. Their gentle nature is the defining characteristic of the breed.

Their energy level is moderate. While Great Dane puppies can be quite rambunctious, adults settle into a relatively calm demeanor. They enjoy daily exercise but are not the tireless athletes that breeds like the German Shorthaired Pointer or Australian Shepherd are. They are content with moderate activity followed by long rest periods.

Great Danes are devoted to their families and want to be included in all household activities. They are friendly with strangers, often approaching new people with curiosity and a wagging tail. While their size alone serves as an effective deterrent, they are not typically aggressive guard dogs.

Despite their imposing presence, Great Danes are sensitive dogs. They respond to their owner’s emotions, wilt under harsh treatment, and need gentle, positive interactions to thrive. A stressed or frightened Great Dane is a significant challenge simply due to the physics of managing a panicked 150-pound animal.

Their puppyhood is memorable — Great Dane puppies grow at an astonishing rate and go through an awkward adolescent phase where they are too big for their coordination. This gangly period can be both amusing and destructive, as an uncoordinated Dane puppy can clear a coffee table with a single tail wag.

Exercise Needs

Great Danes need 30 to 60 minutes of daily exercise. This should include leisurely walks, gentle play, and opportunities to stretch their long legs in a safe environment. Their exercise needs are modest for their size.

The best activities include moderate walks, gentle jogging (once fully mature), free play in a fenced area, and brief games of fetch. Some Danes enjoy swimming, which provides excellent low-impact exercise for their joints.

Exercise moderation is critically important during growth. Great Dane puppies grow extraordinarily fast, and their bones and joints are vulnerable during this period. Avoid high-impact activities, excessive running, rough play on hard surfaces, and any jumping until the dog is at least 18 to 24 months old. Over-exercising a growing Dane can cause lasting orthopedic damage.

Even as adults, Great Danes are not endurance athletes. They are sprinters rather than marathon runners, capable of impressive bursts of speed but not sustained activity. Short, moderate exercise sessions are preferable to long, demanding ones.

Grooming Requirements

Great Danes have a short, smooth coat that requires minimal grooming. Weekly brushing with a rubber curry brush or grooming mitt removes loose hair and keeps the coat healthy. They are moderate shedders.

Bathing can be challenging simply due to the dog’s size. Every six to eight weeks is sufficient, but you will need a large bathing area or may opt for professional bathing services. Self-serve dog wash stations can be a practical solution.

Drooling is significant in Great Danes, particularly those with looser jowls. Keep towels and drool rags handy, especially around meal times. Some Danes drool more than others, but expect some degree of drool management.

Nail trimming every two to three weeks is important. Many Danes are sensitive about their feet, so acclimating them to nail care from puppyhood is essential. Weekly ear cleaning and regular dental care complete the routine.

Common Health Issues

Great Danes face several serious health challenges, many related to their giant size. Bloat (gastric dilatation-volvulus) is the most immediately life-threatening concern. Great Danes are among the breeds at highest risk for this condition, where the stomach fills with gas and can twist on itself. Prophylactic gastropexy is widely recommended and is often performed at the time of spay or neuter surgery.

Dilated cardiomyopathy (DCM) is a major concern in the breed. This condition causes the heart to enlarge and weaken, eventually leading to heart failure. Regular cardiac screening is recommended starting at a young age.

Hip dysplasia affects Great Danes at moderate rates. Osteosarcoma (bone cancer) is a significant concern, particularly in the limbs. Wobbler syndrome (cervical vertebral instability) can cause neurological problems affecting gait and coordination.

Hypothyroidism and certain eye conditions, including entropion and cataracts, are also seen. The harlequin gene requires careful breeding management, as double merle breeding can produce puppies with vision and hearing defects.

Recommended health tests include hip evaluation, a cardiac exam, an ophthalmologist exam, and thyroid screening. An autoimmune thyroiditis test from OFA is also recommended.

Lifespan

The typical lifespan of a Great Dane is 7 to 10 years. This is shorter than most breeds and is directly related to their giant size. Some individuals live longer with excellent care and favorable genetics, but the breed’s short lifespan is one of the most significant realities prospective owners must accept. Every year with a Great Dane is precious.

Cost to Buy and Maintain

Great Dane puppies from reputable breeders typically cost ~$1,500 to ~$3,000. Show-quality or European-line puppies may cost more. Rescue adoption typically costs ~$200 to ~$500.

Annual costs are higher than average due to the breed’s size:

Food: ~$800 to ~$1,800 per year (giant breeds eat significantly more)
Veterinary care: ~$600 to ~$1,500 for routine care, with potential for much higher costs due to health issues
Grooming: ~$100 to ~$300 per year
Pet insurance: ~$600 to ~$1,500 per year (strongly recommended)
Toys, treats, and supplies: ~$300 to ~$600 per year (everything is bigger and more expensive)

Total annual cost of ownership typically ranges from ~$2,400 to ~$5,700. Everything costs more with a giant breed — beds, crates, food, medications, and veterinary procedures are all scaled to the dog’s size.

Best For

Great Danes are ideal for people who love large dogs and have the space to accommodate them. They are well-suited to families who want a gentle, loving companion that also serves as an impressive presence. Despite their size, they can adapt to smaller living spaces if exercise needs are met — many Danes are surprisingly good apartment dogs due to their moderate energy level.

Families with children of all ages can do well with Great Danes, as the breed’s gentle nature extends naturally to kids. People who want a dog with an intimidating appearance but a sweet disposition will find the Great Dane to be a perfect balance.

First-time owners can succeed with Great Danes if they are prepared for the unique challenges of giant-breed ownership and commit to proper training and veterinary care.

Not Ideal For

People who are not prepared for a short lifespan should think carefully about this breed. Losing a beloved companion at seven to ten years of age is an emotional reality of Great Dane ownership.

Those on tight budgets should consider the significantly higher costs of feeding, treating, and housing a giant breed. Everything from food to surgery costs more for a dog this size.

People with very small living spaces may find the practical challenges of a 150-pound dog difficult. While Danes can adapt to smaller homes, they need room to turn around, and their tail alone can cause significant damage in cramped quarters.

Those who want a high-energy exercise partner for intense outdoor activities should look elsewhere. Great Danes are moderate-energy dogs that prefer a gentler pace.

People who cannot tolerate drool should also reconsider. While individual variation exists, drooling is a standard feature of most Great Danes.

Training

Great Danes are moderately easy to train. They are intelligent and generally eager to please, though their sensitivity means training must be positive and encouraging. Harsh corrections can damage their confidence and create fear-based behavioral issues — which are especially problematic in a dog of this size.

Begin training from puppyhood and prioritize basic manners above all else. A 150-pound dog that jumps on people, pulls on leash, or counter surfs creates problems that smaller dogs could get away with. Teaching “sit,” “stay,” “down,” “leave it,” and leash manners should start immediately.

Socialization during puppyhood is important. Expose Great Dane puppies to diverse experiences while they are still small enough to manage easily. Once a Dane reaches adult size, correcting socialization gaps becomes exponentially more difficult.

Common challenges include jumping, counter surfing (their height gives them access to virtually any surface), leash pulling, and spatial unawareness (they do not realize they are too big for certain spaces). Crate training requires a very large crate and should begin while the puppy is small.

Compatibility

With children: Great Danes are generally wonderful with children. Their gentle, patient nature makes them natural companions for kids. The primary concern is accidental injury — a wagging tail, an enthusiastic greeting, or simple clumsiness from a dog this size can knock over small children. Supervision with toddlers is essential.

With cats: Great Danes generally coexist well with cats, particularly when raised together. Their prey drive is typically low, and their gentle nature extends to other household pets. Some Danes are intimidated by cats rather than the reverse.

With other dogs: Great Danes are usually friendly with other dogs. They enjoy canine companionship and are rarely aggressive toward other dogs. Their large size means they should be supervised with much smaller dogs to prevent accidental injury during play.
