14. Great Dane

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. The American Kennel Club notes they can exceed the height of most people when standing on hind legs. A single paw swipe can knock down a person of any size.
