In a word – Unusual
The Bull Terrier appearance needs some getting used to. These funny little power packs have a strong, firm and above-average muscular figure as well as a keen and determined expression. The long oval head is gently shaped downwards with a characteristic egg shaped contour (= down face). The eyes are small, dark and triangular in shape. The ears are small, standing closely together, pointing upwards. The nose is usually black, but can show some pigmentation, and is slightly bent downwards.
The chest should be brad from the front, the body contour well rounded with a short, strong back. The back is slightly arched over the loins. The rib cage should be a little bit visible.
The Bull Terrier tail is short, carried about horizontal, and in the colored versions has a white tip.
The paws are round and compact with well-arched cat-like toes.
According to several sources (Kennel Clubs), different breeds have been bred into the Bull Terrier as we know him today. The main influence are Old English Bulldogs (extinct), Old White English Terriers (extinct) and Dalmatians.
The image below presents the typical features of the standard Bull Terrier and Miniature Bull Terrier:
Today the dog breed can be divided into three appearance subtypes: Mainly Bulldogs, mainly Terriers, mainly Dalmatians. A fourth type is a well balanced mix of the three. While it is said that the “Bulldogs” type often is slightly more leaned back, the “Dalmatian” and “Terrier” types usually show the full temperament of the dominating dog breed.
