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). For decades afterwards, dog fighting clandestinely took place in small areas of Britain. These dogs arrived in America around 1845 to 1860, where the dog fighting practice had continuity and a new American dog breed arrived. In February 10, 1898 the breed was recognized by the United Kennel Club (UKC) named as American Pit Bull Terrier. For some time in the early part of the 20th century the UKC began to register the breed name with the word 'pit' in parentheses (American (Pit) Bull Terrier), to facilitate public acceptance as American Bull Terrier. But this lasted a short time and returned to the previous form. American Pit Bull Terriers with dilute coat colors have not had a higher occurrence of skin allergies as other breeds.
