The American Pit Bull Terrier (APBT) is a purebred dog breed recognized by the United Kennel Club (UKC) and American Dog Breeders Association (ADBA), but not the American Kennel Club (AKC). When compared with the English Staffordshire Bull Terrier, the 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. Consequently, nearly any strain will occasionally throw a red-nosed pup. This means that not every red-nose dog is a true OFRN. Yankee Terrier was another option, also dismissed. The name 'Staffordshire Terrier' was chosen with the claim that the breed originally came from Staffordshire in England. On June 10, 1936 around 50 UKC dogs entered the AKC stud book under the name Staffordshire Terrier. Wilfred Truman Brandon founded the AKC Staffordshire Terrier Club of America (STCA). The Colby dog named Colby's Primo was one of the first to be regarded as an ideal model of the breed standard in the AKC.
