Great Danes are the tallest dog breed in the world and one of the most spectacularly unaware of their own size. They will attempt to sit on your lap. They will lean against you with full body weight as an affection gesture and nearly knock you over. They will try to fit into spaces three times too small for them because you're in those spaces. They are, at heart, very large puppies who want to be close to their people.
Exercise: Less Than You'd Think
Great Danes are not high-energy dogs despite their size. 30-60 minutes of moderate daily exercise is appropriate for most adults. Puppies need significantly less — over-exercising growing Great Danes damages their still-developing joints and is a genuine health risk. No sustained running or jumping for puppies under 18 months.
Bloat: The Most Important Health Risk to Know
Gastric dilatation-volvulus (bloat) is the most life-threatening health risk in Great Danes. The stomach fills with gas and can twist, cutting off blood supply. It is a surgical emergency that kills within hours. Risk factors include eating too fast, exercising immediately before or after meals, and stress. Use a slow feeder at every meal, avoid exercise for an hour before and after eating, and know the signs: unproductive retching, distended belly, restlessness. This is a 911 call for your vet.
Lifespan
Great Danes live 7-10 years on average — shorter than most breeds due to the cardiovascular demands of maintaining a large body. Heart disease is common. This shorter lifespan is the hardest part of Great Dane ownership and worth knowing before you fall in love with one.
Space and Furniture
They're surprisingly adaptable to apartment life given their calm nature — but they need space to lie down comfortably. A supportive dog bed is important for a breed prone to joint issues. And yes — they will take up the entire couch if allowed.
