Great Dane

Temperament

Despite the imposing size, Great Danes are typically gentle and affectionate rather than aggressive, and the trait data reflects moderate rather than extreme energy — a common surprise for people who assume a giant breed needs giant amounts of exercise. Trainability is solidly good, and the breed generally does well with children and other pets, though its sheer size means it's often genuinely unaware of how much space it takes up; 'lap dog behavior in a giant body' is a real and frequent owner complaint rather than an exaggeration.

Living with a Great Dane

Only about 45 minutes of exercise is needed daily — giant breeds are, somewhat counterintuitively, moderate-energy dogs — but the size drives nearly every other consideration. Grooming is minimal for the short coat, yet typical monthly cost runs notably higher than for most breeds ($150-280) simply from food volume and larger medication doses. Lifespan is short even by giant-breed standards, typically 7 to 10 years, one of the clearest illustrations of the inverse relationship between size and longevity across dog breeds. Bloat (gastric dilatation-volvulus) is a severe risk given the breed's deep chest and is a genuine medical emergency — owners need to know the warning signs (unproductive retching, a visibly distended abdomen, restlessness) and act immediately if they appear. Dilated cardiomyopathy is also documented in the breed. Great Dane puppies grow extremely fast — a dog that will weigh well over 100 lbs as an adult can gain several pounds a week during peak growth — and vets specifically recommend large-breed puppy food formulated to slow that growth rate slightly, since too-rapid bone growth is itself linked to skeletal problems in giant breeds. Owners should also budget realistically for a shorter list of dog beds, crates, and car harnesses actually built to giant-breed scale, which often cost notably more than standard sizes.
