The American Pit Bull Terrier (APBT) is a dog breed. It is a medium-sized, solidly built, a short-haired dog whose early ancestors came from the British Isles. A member of the molosser breed group, both the American Staffordshire Terrier and the American Pit Bull Terrier (APBT) were bred from the same lineage, but received different names from the two American kennel clubs; American Staffordshire Terrier was the name given by the American Kennel Club (AKC), and American Pit Bull Terrier by the United Kennel Club (UKC). When compared with the English Staffordshire Bull Terrier (another breed within the type commonly called pit bulls), American Pit Bull Terrier is larger by margins of 6–8 inches (15–20 cm) in height and 25–35 pounds (11–16 kg) in weight. The American Pit Bull Terrier varies in size. Males normally are about 18-19 inches (45-48 cm) in height and around 35-63 pounds (15-29 kg) in weight. Females are normally around 17-18 inches (43-45 cm) in height and 30-57 pounds (13-26 kg) in weight.
The American Pit Bull is medium-sized and has a short coat and smooth well-defined muscle structure. Its eyes are round to almond-shaped, and its ears are small to medium in length, typically half prick or rose in the carriage. The tail is slightly thick and tapers to a point. The coat is glossy, smooth, short, and stiff to the touch. The accepted coat color can vary widely, but, both the AKC and UKC do not recognize merle coloring. Color patterns that are typical of the breed are spotted, brindled, solid, and with points.
Twelve countries in Europe, as well as Australia, Canada, Ecuador, Malaysia, New Zealand, Puerto Rico, Singapore, and Venezuela, have enacted some form of breed-specific legislation on pit bull-type dogs, including American Pit Bull Terriers, ranging from outright bans to restrictions and conditions on ownership. The state of New South Wales in Australia places restrictions on the breed, including mandatory sterilization. The breed is banned in the United Kingdom, in the Canadian province of Ontario, and in many locations in the United States.
