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.

Living with a Great Dane in Calgary
This section is specific to Calgary (Canadian Food Inspection Agency (CFIA)). The rest of this guide applies to the breed anywhere.

Toronto dog licence required annually from Toronto Animal Services: CAD $32/year (sterilised) or CAD $78/year (unsterilised); microchipping strongly encouraged. Source: Toronto Animal Services (toronto.ca/community-people/animals-and-pets/pets-in-the-city/dogs/).
Climate & exercise in Calgary
Calgary is humid continental; cold winters (Jan avg -5°C, windchill to -20°C); warm humid summers (Jul avg 27°C); road salt season November through March. walk before 8am or after 7pm in July and August; pave test before midday walks — Toronto pavement can exceed 55°C in direct summer sun. Toronto's humid summer heat raises risk for brachycephalic breeds (French Bulldog, Pug, Bulldog) in July–August; road salt and ice-melt chemicals on sidewalks November–March require paw-washing after every winter walk; the Rouge Valley and Don Valley ravines are prime Ixodes scapularis tick habitat.
Parasite prevention
Plan for Lyme disease tick (Ixodes scapularis, blacklegged tick) present in Toronto ravines and Rouge National Urban Park — prevention April through November; heartworm prevention June through November (Ontario mosquito season); road salt paw protection November through March.
