Great Dane

Giant; 110–175 lbsModerate7–10 years lifespan

Who this breed is NOT for

Tight budgets (everything costs more), anyone who won't train a giant dog, or those who'd struggle with a heartbreakingly short life expectancy.

Bred to do

Originally bred to hunt boar and guard estates — now a gentle giant companion. Enormous size, surprisingly moderate energy.

Exercise needs

Moderate — daily walks and space to stretch, but not a high-endurance athlete. Careful with exercise while young; their joints and growth plates need protecting.

Temperament

Gentle, affectionate, calm, people-oriented — a true 'gentle giant.' Often thinks it's a lap dog. Can be sensitive and a bit timid without socialization.

Trainability

Moderate — willing and food-motivated, but training is non-negotiable: an untrained 150-lb dog is genuinely unmanageable. Early manners are essential.

With kids & pets

Usually wonderful with both — gentle and tolerant — but sheer size means supervision with small children (an accidental bump knocks a toddler flat).

Living situation

Adaptable, even to larger apartments given their moderate energy — but they take up enormous space, and everything (food, beds, meds, boarding) costs more.

Grooming & shedding

Short coat, easy grooming, moderate shedding. Some drool.

Health & costs

The hard truth: giant breeds live short lives (7–10 years) and are prone to bloat (a fast, fatal emergency — learn the signs), heart disease, and joint problems. Vet care, food, and even medication doses cost far more at this size. Pet insurance strongly recommended.

Best fit

People who want a calm, affectionate giant, have the space and budget, and can emotionally handle a shorter lifespan.

A note from Kerri

Great Danes are some of the sweetest dogs alive — gentle, cuddly, and dignified. But go in clear-eyed: they're expensive at every turn, bloat is a real danger, and you get far too few years. Worth every one of them, if you're ready for that trade.
