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

This section is specific to Barcelona (Ajuntament de Barcelona / Col·legi de Veterinaris de Barcelona). The rest of this guide applies to the breed anywhere.

This breed is not eligible for Protectora de Animals de Barcelona / CAAD.
Licensing
All dogs must be registered in the cens municipal d'animals de companyia at the Ajuntament de Barcelona (cita prèvia: ajuntament.barcelona.cat/tramits); microchip required; annual rabies vaccination recommended though Spain (mainland) is rabies-free since 1978. PPP licence holders also require mandatory civil liability insurance (seguro de responsabilidad civil). Source: Ajuntament de Barcelona; Ley 7/2023 de Bienestar Animal.
Climate & exercise in Barcelona
Barcelona is Mediterranean; hot dry summers (Jun–Sep, 28–33°C); mild winters (Dec–Feb, 8–14°C); spring and autumn pleasant; occasional cold tramuntana wind from north. walk before 9am or after 7pm in July and August; pavement in direct sun on the Rambla and Barceloneta can reach 50°C+ at midday — test with your hand; sea breeze from the Mediterranean provides relief near the waterfront from mid-afternoon. Barcelona's Mediterranean heat peaks July–August (28–33°C with high coastal humidity); brachycephalic breeds (French Bulldog, Bulldog, Pug, Shih Tzu) face elevated heatstroke risk — limit outdoor exercise to early morning or evening during heat peaks. Leishmania is the most significant endemic canine disease in Catalonia: transmitted by sand flies active from dusk to dawn May–October; preventive treatment (collar or spot-on/oral) plus annual serological screening is strongly recommended by Catalan vets.
Parasite prevention
Plan for year-round flea prevention essential (mild winters mean no flea-kill season in coastal Catalonia); Leishmania risk (Leishmania infantum, transmitted by sand flies Phlebotomus perniciosus) is significant in Barcelona — monthly preventive collar or oral treatment recommended May through October; tick prevention for dogs accessing Collserola Natural Park, Serralada de Marina, and inland areas year-round; heartworm (Dirofilaria immitis) risk in coastal areas — annual prevention recommended.

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.
