Bulldogs are never mistaken for other breeds of dogs. They are a medium-size dog with a thick-set, low-slung body. Their short-muzzled head is massive and square. They have broad shoulders and chests, with thick, sturdy limbs.
Although Bulldogs are low to the ground, they are wide and muscular. Their broad heads have cheeks that extend to the sides of their eyes, and the skin on their foreheads should have dense wrinkles. A Bulldog has a droopy upper lip and his lower jaw is undershot, meaning that his lower teeth stick out farther than his top teeth. The Bulldog’s jaws are massive and strong, intended for latching on to his opponent and holding on.
Bulldogs have round, dark eyes. Their ears are small and thin, folded back like a rose. Their short tails are carried low on their rumps.
