The American Bully is a recently formed companion dog breed, originally recognized by the American Bully Kennel Club (ABKC). It has been recognized by the United Kennel Club (UKC) since July 15, 2013. It is a small to large breed which has been divided into four categories by some registering organizations, Pocket, Standard, Classic and XL. Other organizations, including the UKC, have 1 consistent size standard. While some of the founding kennels, namely Razor's Edge owner Dave Wilson, affirmed that they used only the two first aforementioned breeds to produce the desired dogs, it is consensus that at least five other breeds were used to attain the more 'bully' physical traits desired. These are assumed to be the American Bulldog, English Bulldog, Olde English Bulldogge, Staffordshire Bull Terrier and French Bulldog. Within the ABKC, the four varieties are separated by height without specification of weight. All these varieties are expected to follow the same standard with minor alterations.
