Pitbull Dog

Dogs termed pit bulls share similar physical characteristics, but the morphological variation among bully breed dogs makes it difficult for even experts to visually identify them as distinct. While mixed-breed dogs are often labeled as pit bulls if they have certain physical characteristics, such as a square-shaped head or bulky body type, visual identification of mixed-breed dogs is not recommended by the scholarly community. Some of the breeds which often get mistaken for pit bulls (but which are not genetically pit bulls) include the Cane Corso, Dogo Argentino, Dogue de Bordeaux, and others, but because these breeds did not originate with the crossbreeding of bulldogs and terriers, they do not fall under the term "pit bull".
