Great Dane
A German boarhound turned gentle housemate. Moderate exercise needs and quiet indoors, but growth must be managed carefully and the bloat risk is among the highest of any breed.

Weight and lifespan are reference ranges from the breed guide. They vary by sex, lineage and individual dog and do not predict your dog’s ideal weight or lifespan. Read the care descriptions alongside the individual dog’s history.
Background and characteristics
Despite the name, the Great Dane is a German breed, developed to hold boar and later refined into an estate guardian and companion. The modern dog is soft, people-focused and often surprisingly sensitive. Harsh handling backfires; clear signals and praise work.
It also has no apparent awareness of its own size, so leaning on people and attempting to use the sofa are standard behaviours rather than training failures.
Exercise and play
Exercise is moderate. An adult does well on two walks of thirty to forty-five minutes plus a short run in a safe space. Puppies are a different problem entirely.
The skeleton is still growing at two years, so repeated stairs, jumping and long jogs load joints that cannot take it, and forced roadwork is a genuine cause of later lameness. Diet matters just as much: an energy-dense, calcium-rich food that pushes fast growth raises the risk of developmental bone disease, so use a large-breed puppy formula and keep the dog lean.
Coat and everyday care
Coat care is trivial - a rubber brush once a week - though the sheer surface area means more shed hair than a short coat suggests. Keep nails short, because a dog this heavy on long nails changes how it loads its feet.
Health considerations
The health headline is gastric dilatation-volvulus. Great Danes sit at the top of the risk tables, and many owners discuss prophylactic gastropexy with their vet at the time of spay or neuter. Learn the signs now: a distended abdomen, unproductive retching and restlessness are an immediate emergency.
Also on the list are dilated cardiomyopathy, cervical spondylomyelopathy (wobbler syndrome), osteosarcoma and hip dysplasia. Expect seven to ten years.
Home environment and care planning
Practically, a Great Dane can live in a flat, because indoors it mostly lies down. What it cannot live with is polished flooring: run rugs along every route the dog uses, since a slipping seventy-kilo dog is a joint injury waiting to happen. Confirm your car can carry the dog and your clinic can handle one, and be realistic that food, medication and boarding all scale with weight.
In hot weather the long muzzle helps compared with mastiff types, but a body this large still stores heat, so keep summer exercise early; in winter the thin coat means a real dog coat in a cold climate.
