Great Dane
Also known as: Deutsche Dogge, German Mastiff, Apollo of dogs
The "Apollo of dogs" - a giant, elegant breed that is gentle, affectionate and surprisingly calm indoors despite its towering size. Great Danes are devoted, sociable and famously good with children, combining an imposing presence with a sweet, patient temperament that wins over everyone they meet.
Origin and purpose
Despite the name, the Great Dane is a German breed (Deutsche Dogge), refined in the 19th century from large boarhounds used to hunt wild boar and guard estates. Selective breeding turned the working boarhound into the towering, dignified companion recognised today.
Temperament
Breed authorities describe the Great Dane as friendly, patient and dependable — a "gentle giant" that is good with children and usually sociable with other dogs, often convinced it is a lap dog. It is moderate in energy and trainable with early, gentle guidance. As with any breed, individual temperament varies far more than the label implies (Morrill et al., Science 2022).
Health and longevity
Giant size comes at a cost: Great Danes are one of the breeds at highest risk of gastric dilatation-volvulus (bloat), which is why many owners and breeders opt for a prophylactic gastropexy. Controlled growth in puppyhood and lean body condition matter enormously.
Common health conditions
Living with a Great Dane in Hanoi
This section is specific to Hanoi (Department of Animal Health (DAH) / MARD). The rest of this guide applies to the breed anywhere.
Hanoi Pet Rescue / VAWO: Not eligible
This breed is not eligible for Hanoi Pet Rescue / VAWO.
Licensing
Dog registration required under Decree 90/2017/ND-CP: register with the local ward/commune People's Committee; annual rabies vaccination mandatory for registration; fine for unregistered dogs. Hanoi has periodically run dog-catching drives for stray/unleashed dogs in the inner districts — keep dogs leashed and registered. Microchipping not nationally mandatory but strongly recommended.

Climate & exercise in Hanoi
Hanoi is humid subtropical (northern Vietnam) with four seasons — hot humid summer (May–September, 30–39°C, heavy rain), a short pleasant autumn (Oct–Nov), a cool-to-cold winter (December–February, 10–20°C, occasional dips below 12°C with cold drizzle "mua phun"), and a humid spring (Mar–Apr); far more seasonal variation than tropical HCMC. summer (May–Sep): walk before 7:30am or after 6:30pm — midday heat + humidity is dangerous; winter (Dec–Feb): daytime walks are comfortable but small/short-coated dogs (and puppies/seniors) need a coat on cold drizzly days below ~15°C. Hanoi's four-season climate means care shifts through the year: summer (May–September) brings HCMC-level heat + humidity where midday exercise is dangerous for brachycephalic breeds (French Bulldog, Pug, Shih Tzu), while the cool-to-cold winter (December–February) is comfortable for walks but cold drizzly spells warrant a coat for small or short-coated dogs. Year-round parasite prevention and annual rabies vaccination (a legal requirement under Decree 90/2017/ND-CP) remain non-negotiable — any animal bite in Vietnam requires immediate medical attention and post-exposure prophylaxis.
Parasite prevention
Plan for year-round heartworm prevention recommended (mosquitoes active most of the year; risk lower in the coolest winter weeks but do not lapse); tick-borne disease (Ehrlichia canis, Babesia, Hepatozoon canis) high risk, Rhipicephalus sanguineus endemic; mange common; intestinal parasites endemic; leptospirosis risk in the summer wet season. Annual rabies vaccination legally required — Vietnam is NOT rabies-free..
Cost of ownership in Hanoi
Local Great Dane cost figures for Hanoi are being verified. Budget for purchase or adoption, initial setup, food, grooming, routine veterinary care, parasite prevention and pet insurance. Figures are quoted in ₫.
Health & longevity
Responsible breeders health-test their breeding dogs. Ask to see current certificates before committing.
Nutrition note: Giant-breed puppy diet with controlled calcium/energy to slow growth and protect joints; raised, multiple small meals and rest after eating to lower bloat risk.

Cost of ownership
FLAG: indicative Singapore estimate — very high food and medication doses by weight; short lifespan offsets some lifetime total.
