The Great Dane is not a miniature horse but a massive dog. Usually gentle and patient with children, they can stand up to 32 inches at the shoulder. Great Danes are vigilant and must adapt to home life, as their calm nature can change quickly. According to the American Kennel Club, they can reach greater heights than most people when on their hind legs. With a single paw swipe, a Great Dane can knock down a person of any size.
