You can’t mistake a Bulldog for any other breed. The loose skin of the head, furrowed brow, pushed-in nose, small ears, undershot jaw with hanging chops on either side, and the distinctive rolling gait all practically scream “I’m a Bulldog!” The coat, seen in a variety of colors and patterns, is short, smooth, and glossy. Bulldogs can weigh up to 50 pounds, but that won’t stop them from curling up in your lap, or at least trying to. But don’t mistake their easygoing ways for laziness—Bulldogs enjoy brisk walks and need regular moderate exercise, along with a careful diet, to stay trim.
