Despite the name, Great Danes are German. They descend from the boar hounds of German nobility, mastiff and greyhound-type crosses, and some slept in their owners' bedrooms as guards. The result is one of the tallest dogs, typically 28 to 32 inches and 110 to 175 pounds, with a long head, a short smooth coat and a square, elegant frame.
Many Danes are gentle, friendly and surprisingly calm at home, often happy to lean on their people or sprawl across the sofa. Size still shapes everything: food bills, car space, careful puppy growth, and a real risk of bloat and heart disease within a lifespan that is often under ten years. Dogs of the breed vary, so a dog's own personality and health matter as much as its breed.
