Great Dane: Temperament, Care & Lifespan

Trait Score Snapshot

Size & lifespan

Great Danes are among the largest dog breeds by height.

• Males: typically 120–175 lbs, 30–32 inches at the shoulder
• Females: typically 99–130 lbs, 28–30 inches at the shoulder

The average lifespan is 7–10 years — shorter than most breeds due to the metabolic demands of their giant size. Some lines may live beyond 10 years; others, particularly those with cardiac predispositions, may not reach 8. Understanding this before committing is important.

History & origin

Despite the name, the Great Dane has no meaningful connection to Denmark. The breed was developed in Germany — likely from large hunting dogs including crosses of English Mastiffs and Irish Wolfhounds — primarily for hunting wild boar. These powerful dogs needed both the size to pursue large game and the steadiness to hold it.

By the 1600s, German nobility kept these dogs as estate guardians and symbols of status. The breed was refined over subsequent centuries toward its modern temperament: less aggressive than its hunting-dog ancestors, more sociable, and better suited to family life.

The American Kennel Club recognized the Great Dane in 1887. Today the breed is consistently popular as a companion, known as much for its gentle personality as its dramatic size.

Lifestyle fit

• Apartment Living: Possible only with daily exercise and a large enough living space — most do better in homes
• First-Time Owners: Moderate challenge — calm temperament helps, but size and health complexity are significant commitments
• Families with Kids: Often a strong fit in households with older children and clear boundaries
• Active Households: Moderate fit — they enjoy daily activity but are not high-drive
• Low-Energy Homes: Reasonable fit — Great Danes are calmer indoors than most large breeds

Quick take: Is a Great Dane right for you?

Best for

• Families or individuals with enough living space for a very large dog
• Owners prepared for above-average veterinary and food costs
• Households where someone can commit to early obedience training
• People who want a loyal, calm large companion that is not physically high-maintenance

Not ideal for

• Small apartments without room for a giant-breed dog to move comfortably
• Owners unprepared for a short lifespan and potential late-life health expenses
• Very active households expecting a high-endurance athletic breed
• Families with small toddlers who may be knocked over by accidental contact

Temperament & personality

Great Danes are generally friendly, patient, and affectionate dogs that tend to be sociable with both people and other animals.

Gentle but not timid

Many Great Danes are confident without being aggressive. They are not typically reactive or easily startled. Their sheer size can deter unwanted visitors, but their default temperament is usually approachable — not guarded or independent.

Affectionate and family-oriented

Most Great Danes form strong bonds with their household members and actively seek close contact. This breed is not well-suited to life alone outdoors or isolated from the family. They often behave more like oversized lap dogs than aloof guardians.

Sensitive disposition

Great Danes tend to respond well to calm, patient handling. Harsh or correction-heavy training methods are generally counterproductive — this breed typically learns better through consistency and encouragement.

Socialization still matters

Despite a naturally outgoing disposition, early exposure to different environments, people, and animals improves confidence and reduces the chance of stress-related behavior in unfamiliar settings. A Great Dane that was not well-socialized as a puppy can become anxious or reactive in busy public environments.

Exercise needs

Great Danes have moderate exercise needs — less than you might expect for a dog of this size.

Most adult Great Danes do well with 30–60 minutes of daily activity, split between walks and some free movement time. High-intensity activities like running should be limited, especially in puppies, because excessive impact exercise during growth can stress developing joints.

A typical routine may include:

• Two moderate leash walks daily
• Occasional off-leash time in a safely enclosed area
• Low-impact enrichment such as sniff walks or short training sessions

Puppy exercise caution

Great Dane puppies grow at a rapid rate, and joint development is not complete until approximately 18–24 months. Forced repetitive exercise — long runs, stair drills, prolonged jumping — during this phase can contribute to orthopedic problems that affect the dog's quality of life long-term. Short, calm walks are preferable for young Great Danes.

Shedding & grooming

Shedding

Great Danes have short, sleek coats and shed at a moderate level year-round. While individual hairs are short, the volume accumulated from a large body surface area is noticeable on furniture and dark clothing. A weekly brush-down reduces the amount shed into the environment.

Grooming routine

Grooming demands are low relative to most breeds:

• Weekly brushing with a rubber grooming mitt or soft bristle brush
• Bathing every 6–8 weeks or as needed (bathing a 150+ lb dog requires some preparation)
• Routine nail trimming, ear checks, and dental care

Professional grooming is rarely necessary for Great Danes, though some owners seek it for convenience.

Are Great Danes good with kids?

Great Danes can be excellent family dogs, particularly for families with older children. They are generally patient and gentle in temperament.

The primary concern with young children is physical: a friendly, well-meaning Great Dane can knock over a small child without any intention of doing so. Supervision around toddlers is important not because of aggression but because of sheer size.

With older children who know how to interact calmly, most Great Danes are loyal and affectionate companions that rarely show aggression toward family members.

Are Great Danes good for apartments?

Great Danes can adapt to apartment life in some cases, but only with enough indoor space, calm building logistics, and consistent daily exercise. Practicalities matter:

• The apartment must have enough floor space for the dog to move, stretch, and turn around without cramping
• Daily outdoor exercise is non-negotiable
• Building infrastructure (elevators, narrow hallways, stairs) requires a dog that is comfortable navigating close quarters calmly
• Neighbor awareness of a large dog moving around overhead or in shared spaces is relevant

In buildings with reliable outdoor access and a committed daily walk routine, some Great Danes live contentedly in apartments. In cramped spaces without adequate exercise, management becomes difficult for both dog and owner.

Cost to own a Great Dane

Great Danes are among the more expensive breeds to own, primarily because of size-driven costs:

• Food: A Great Dane may consume 6–10+ cups of kibble daily — budget significantly above smaller breeds
• Veterinary care: Drug dosages, surgical supplies, and procedures all scale with body weight
• Pet insurance: Worth serious consideration given GDV risk and cardiac susceptibility in the breed
• Equipment: Larger beds, crates, harnesses, and elevated food bowls add meaningful cost over time

Training investment early is also worthwhile. A well-trained 30 lb dog is a minor inconvenience when rambunctious; an untrained 150 lb dog is a significant management and safety challenge.
