GENERAL APPEARANCE: The Boston Terrier is a live­ly, high­ly intel­li­gent, smo­o­th coa­ted, short-hea­ded, com­pact­ly built, short-tai­led, well balan­ced dog. Its brindle is black or seal in colour (seal is defi­ned as appea­ring black except it has a red cast when viewed in the sun or bright light) and even­ly mar­ked with whi­te. The head is in pro­por­ti­on to the size of the dog. The expres­si­on indi­ca­tes a high degree of intel­li­gen­ce. The body is rather short and well knit, the limbs strong and well for­med, and the tail is short. No fea­tu­re is so pro­mi­nent that the dog appears badly pro­por­ti­o­ned. The dog con­veys an impres­si­on of deter­mi­nati­on, stren­gth and acti­vi­ty, with sty­le of ele­gan­ce; carri­a­ge is easy and gra­ce­ful. A pro­por­ti­o­na­te com­bi­nati­on of colour and whi­te mar­kings is a par­ticu­lar­ly dis­tincti­ve fea­tu­re of a good repre­sen­ta­ti­ve spe­ci­men.
Balance, expres­si­on, colour and whi­te mar­kings should be given par­ticu­lar con­si­de­rati­on in deter­mi­ning the rela­ti­ve value of the gene­ral appea­ran­ce to other points.
The cle­an-cut short bac­ked body of the Boston Terrier coupled with the unique cha­rac­te­ris­tics of its squa­re head and jaw, and its stri­king mar­kings have resul­ted in a most dap­per and char­ming American ori­gi­nal: The Boston Terrier.
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 the dog’s wei­ght and structu­re.

NATURE / 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 an incom­pa­ra­ble com­pa­ni­on.

HEAD:
CRANIUM:
The skull: squa­re, flat on top, free from wrin­kles, brow abrupt.
The stop: well defi­ned.

FACIAL FEATURES:
The nose: The nose is black and wide, with a well defi­ned line between the nos­trils. Well open nos­trils.
The muzzle: short, squa­re, wide and deep and in pro­por­ti­on to the skull. It’s 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 stop to end of the nose is paral­lel to the top of the skull.
The chops: The chops are of good depth, but not pen­du­lous. Completely cover the teeth when the mou­th is clo­sed.
The jaw/teeth: The jaw is broad and squa­re with short regu­lar teeth. The bite is even or suf­fi­ci­ent­ly under­shot to squa­re the muzzle.
Cheeks: Flat.
Eyes: wide apart, lar­ge and round and dark in colour. Set squa­re in the skull and the out­si­de cor­ners are on a line with the che­eks as viewed from the front.
The expres­si­on: alert and kind, indi­ca­ting a high degree of intel­li­gen­ce. The expres­si­on is the most impor­tant attri­bu­te of the bre­ed.
The 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 under­li­ne the ove­rall balan­ce to the dog’s body. It is sli­ght­ly arched, carry­ing the head gra­ce­fully and setting neat­ly into the shoul­ders.

BODY: The body should appear short.
The topli­ne: level.
The back: just short enou­gh to squa­re the body.
The rump: cur­ves sli­ght­ly to the set-on of the tail.
The chest: deep with good wid­th. Ribs well sprung and carried well back to the loins.

TAIL: set on low, short, fine and tape­ri­ng, strai­ght or screw. Must not be carried abo­ve the hori­zon­tal. (Note: The pre­ferred tail does not exce­ed in len­gth more than one-quar­ter the distan­ce from set-on to hock.)

LIMBS:
THE FORELEGS The fore­le­gs are set rela­ti­ve­ly wide apart and on a line with the upper tip of the shoul­der bla­des; strai­ght in bone.
The shoul­ders: slo­ping and well laid back, which allows for the Boston Terrier’s cha­rac­te­ris­tic move­ment.
The elbows: stand nei­ther in nor out.
Pasterns: short and strong. The dewc­la­ws may be remo­ved.
The fore­fe­et: small, round and com­pact, tur­ned nei­ther in nor out. With well arched toes and short nails.

THE HIND LEGS:
The thighs: strong and well muscled, set true.
Stifles: well bent.
The hocks: short, tur­ning nei­ther in nor out, with a well defi­ned hock joint. Hind feet: small and com­pact, with short nails.

GAIT: The gait of the Boston Terrier is that of a sure foo­ted, strai­ght gai­ted dog, fore­le­gs and hind legs moving strai­ght ahe­ad in line with per­fect rhy­thm, each step indi­ca­ting gra­ce and power.

COAT:
COAT: The coat is short, smo­o­th, bright and fine in tex­tu­re.

COLOUR: brindle, black or seal (seal is defi­ned as appea­ring black except it has a red cast when viewed in the sun or bright light), with whi­te mar­kings. Brindle is pre­ferred only if all other qua­li­ties are equal.
Required Markings: White muzzle band, whi­te bla­ze between the eyes, whi­te fore chest.
Desired Markings: White muzzle band, whi­te bla­ze between the eyes and over the head, whi­te collar, whi­te fore chest, whi­te on part or who­le of fore­le­gs and hind legs below the hocks. (Note: A repre­sen­ta­ti­ve spe­ci­men should not be pena­li­zed for not possessing “Desired Markings”.)
A dog with a pre­pon­de­ran­ce of whi­te on the head or body must possess suf­fi­ci­ent merit otherwi­se to coun­ter­act its defi­ci­encies.

Weight is divi­ded by clas­ses as follows:
— Under 15 pounds (6.8 kg);
— 15 pounds and under 20 pounds (6.8 to 9 kg);
— 20 pounds and not exce­e­ding 25 pounds (9 to 11.35 kg).
