Great Danes are German, not Danish. They descend from the boar hounds of German nobility, mastiff and greyhound-type crosses, and Germany named the breed Deutsche Dogge in 1878. Males stand 30 to 32 inches or more and females 28 to 30, with a short coat, a long chiseled head and a square, elegant frame.
Many Danes are gentle, friendly and calm at home, though some are alert watchdogs that bark at visitors. Size shapes daily choices: a vehicle with room, a sturdy bed and a plan for snowy months. Expect a lifespan that's often seven to ten years, and real risks of bloat and heart disease. Dogs vary, so the dog's own personality matters more than the breed label.
