Often called the gentle giant — Great Danes are calm, affectionate, and famously large. Their short lifespan is the hardest part of ownership; everything else is manageable with space and dedication.
Great Dane temperament
Calm, gentle, and patient. 'Velcro dogs' — they lean on family members constantly. Generally good with kids but their size requires supervision.
History in Australia
Developed in Germany in 1700s from boarhounds and Mastiffs. Originally bred for boar hunting, later refined as companions.
Who the Great Dane suits
Good for:
- Experienced giant-breed owners
- Homes with space
- Calm families
- Owners who've researched short giant-breed lifespan
Watch out for:
- Short lifespan (7–10 years)
- Bloat risk extremely high
- Cardiomyopathy common
- Orthopaedic issues during growth
Training a Great Dane
Start training at 8 weeks — you cannot physically manage a 50kg untrained dog. Positive reinforcement, short sessions. Limit forced exercise during growth (12+ months) to prevent joint damage.
Common Great Dane health issues
- Bloat (gastric torsion)
- Dilated cardiomyopathy
- Hip/elbow dysplasia
- Osteosarcoma
- Wobbler syndrome
Insurance note: High premiums due to short lifespan and major condition risks (bloat, cardiomyopathy, bone cancer). Confirm the policy has no age cutoff at 8 — many Great Danes need cover most around then.

Frequently asked questions
How long do Great Danes live?
7–10 years is typical — among the shortest of any dog breed. Gastric torsion (bloat) and heart disease are the most common causes of premature death.
How much do Great Danes eat?
A lot — 5–8 cups of premium large-breed kibble daily for an adult. Food cost runs $220–350/month. Factor this into your budget.
Are Great Danes good apartment dogs?
Surprisingly, moderate-size apartments can work for calm adults — they sleep most of the day and need only moderate exercise. Giant puppies are harder — space and stair-free access matter during growth.
