Do you know the Bulldog is the official mascot of the United States Marine Corps, and thirty-nine American universities use a Bulldog as their mascot? This friendly, gregarious, and willful breed is quite impressive, huh? he Bulldog is among dogdom's most easily recognized citizens: 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 scream “I'm a Bulldog!” from a block away. The Bulldog coat, seen in a variety of colors and patterns, is short, smooth, and glossy. The sum of these parts is a thick-set, low-slung, well-muscled bruiser whose distinctive "sourmug" face has become the universal symbol of courage and tenacity.
