The American Pit Bull Terrier must be both powerful and agile so actual weight and height are less important than the correct proportion of weight to height. Desirable weight for a mature male in good condition is between 35 and 60 pounds. Desirable weight for a mature female in good condition is between 30 and 50 pounds. Dogs over these weights are not to be penalized unless they are disproportionately massive or rangy.
