OFFICIAL STANDARD

 

Country of origin: USA
FCI Classification, the 9th group, Companions and Toys
General Appearance - The Boston Terrier is a lively, highly intelligent, smooth coated, short-headed, compactly built, short-tailed, well balanced dog, brindle, seal or black in color and evenly marked with white.  The head is in proportion to the size of the dog and the expression indicates a high degree of intelligence.
The body is rather short and well knit, the limbs strong and neatly turned, the tail is short and no feature is so prominent that the dog appears badly proportioned.  The dog conveys an impression of determination, strength and activity, with style of high order; carriage easy and graceful.  A proportionate combination of "Color and White Markings" is a particularly distinctive feature of a representative specimen.
In a comparison of specimens of each sex, the only evident difference is a slight refinement in the bitch's conformation.
Important proportions - The length of leg must balance with the length of body to give the Boston Terrier its striking square appearance.  The Boston Terrier is a sturdy dog and must not appear to be either spindly or coarse.  The bone and muscle must be in proportion as well as an enhancement to the dog's weight and structure.
Behaving/ Temperament - The Boston Terrier is a friendly and lively dog.  The breed has an excellent disposition and a high degree of intelligence, which makes the Boston Terrier and incomparable companion.

HEAD
Skull - The skull is short, flat on top, free from wrinkles, cheeks flat, brow abrupt and the stop well defined.  The ideal Boston Terrier expression is alert and kind, indicating a high degree of intelligence.
Stop - well bolded

FACE
Muzzle -  is short, square, wide and deep and in proportion to the skull.  It is free from wrinkles, shorter in length than in width or depth; not exceeding in length approximately one-third of the length of the skull.  The muzzle from the stop to end of the nose is parallel to the top of the skull.
Jaw - is broad and square with short regular teeth. 
Mouth - of good depth, but not pendulous, completely covering the teeth when the mouth is closed. 
Teeth - short and regular. The bite is even or sufficiently undershot to square the muzzle. 
Cheeks - flat.
Eyes - The eyes are wide apart, large and round and dark in color.  The eyes are set square in the skull and the outside corners are on a line with the cheeks as viewed from the front.
Expression - alert, kind and pleasant. It indicates a high degree of intelligence.
Ears - small, carried erect, either natural or cropped to conform to the shape of the head and situated as near to the corners of the skull as possible.
Neck - The length of neck must display an image of balance to the total dog.  It is slightly arched, carring the head gracefully and setting neatly into the shoulders.

Hips - curves to the set-on of the tail.
