The name “Pitbull”, which translates to “bull of the arenas”, in reference to its past as a fighter, is also often the nickname given to the American Pitbull Terrier. In a more general way, it designates dogs resulting from crosses which lead to morphological resemblances with the American Pitbull Terrier. Only certain dogs can be registered with the United Kennel Club (UKC).

Pit bull

Contrary to popular belief, the Pitbull is not part of the Molossoids. It is his extremely muscular and powerful body that is the cause of this common mistake. The Pitbull is short and smooth, but the coat can be one-tone or two-tone and all colors can be represented as well. Its wide and straight limbs give it a very stable base and its wide and slightly inclined hips allow it to take sudden and powerful starts.

Its head, which seems round when viewed from the front, on the contrary, gives the impression of being in the shape of a cone when seen from above, which is one of the specificities of Pitbulls. The muzzle is broad and a little advanced. The jaw muscles are highly developed. Oval, dark eyes and semi-erect ears lighten this portrait and give a soft and intelligent expression to the Pitbull

Its square skull with a pronounced stop shows marked wrinkles when the dog focuses on a subject. The wrinkles are organized around a short muzzle, which is only a third of the length of the head. The lower jaw is wide and the dog may be very slightly prognathic, but this is not a quality. The dark or hazel eyes separated by a frontal wrinkle and the pointed ears but folded back and set back emphasize the square shape of the head. The tail is long and carried downwards.
