Just for clarity's sake for the OP... The excerpt from the UKC standard... Height and Weight 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. and from the ABDA standard in reference to what is desired... Above all, the American Pit Bull Terrier should appear to be an all around athlete. His body is called upon for speed, power, agility and stamina. He must be balanced in all directions. Too much of one thing, robs him of another. In his ideal form, he is a thing of beauty. and from the AADR's standard... SIZE The breed has Historically been of great size variation, however, Males are perferred not over 70 pounds and Females are perferred not over 60 pounds, as extremely large dogs seldom show fluid and agile movement.
