The American Pit Bull Terrier has a shoulder height of 46-56 cm (18-22 in) and generally weighs between 30-70 lb. Pit Bull sizes do vary, however, and so more important than actual weight and size is the dog's proportion. American Pit Bull Terriers have highly set, pointy ears which may be cropped, a broad head, wide cheeks, short back and tail (undocked), and wide, straight forelegs.
