i look at alot of these breeder websites and there are too many out there who seem to be focused on breeding for size, musculature, or color.
not saying anything is wrong with those dogs. its just that they are not breeding to the standards of what the true apbt should look like.
General Appearance
The American Pit Bull Terrier is a medium-sized, solidly built, short-coated dog with smooth, well-defined musculature. This breed is both powerful and athletic. The body is just slightly longer than tall, but bitches may be somewhat longer in body than dogs. The length of the front leg (measured from point of elbow to the ground) is approximately equal to one-half of the dog's height at the withers. The head is of medium length, with a broad, flat skull, and a wide, deep muzzle. Ears are small to medium in size, high set, and may be natural or cropped. The relatively short tail is set low, thick at the base and tapers to a point. The American Pit Bull Terrier comes in all colors and color patterns. This breed combines strength and athleticism with grace and agility and should never appear bulky or muscle-bound or fine-boned and rangy.
Head
The APBT head is unique and a key element of breed type. It is large and broad, giving the impression of great power, but it is not disproportionate to the size of the body.......
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.
