The Boston Terrier’s coat is smooth and shiny: with a tie, its formal attire is complete!
The Boston Terrier has a Terrier Body, but with a short and characteristic head. It is not a toy dog, but a medium size, in any of its three weight varieties: less than 7.5 kg; between 7.5 and 10 kg; and between 10 and 12.5 kg according to the AKC standard; for the FCI it is less than 7 kg; from 7 to 8.5 kg and from 8.5 to 11 kg. The male should not exceed the maximum limit of 12.5 kg. The coat is smooth, bristle color, black or seal (black with a red shine) combined with snow white distributed symmetrically in a stripe over the muzzle, forehead and chest and preferably also on the legs (the AKC admits every color and mark). This is a robust dog with a balanced and compact build; it should never appear thin or coarse, square or chubby. The head, a breed trademark, is square in the skull, flat on the top, with flat cheeks, no wrinkles, abrupt brows and well defined stop. The eyes are well separated and dark (never blue). The muzzle is short and square, deep and wide. The nose should be black, and not Dudley. The jaw is square and the bite should be leveled, or with a slight inferior prognathism. Pronounced prognathism should be avoided. The body displays a short back, and the tail is low inserted and straight or screwed, never docked. To ease the Terrier style movement, the shoulders should be sloped and well set back, and the limbs should be strong.
WHO is a BOSTON TERRIER Owner              
Exceptional with children and as a house dog, the Boston Terrier is a relaxed and responsible gentleman from New England. It is terribly clean and doesn’t have a dog odor, for which it is an easy to care for partner. Although somewhat large as a lap dog, most owners don’t seem to mind the extra weight! At home it is calm and well behaved, besides being an excellent guardian. The Boston Terrier is usually peaceful, but due to its origins, it can defend itself perfectly.
The Boston Terrier’s main trait is its head: it should have a white lace; the muzzle short and square; the eyes well separated. The prominent and bulgy eyes are prone to injury if the game is too rough.
Raising a BOSTON TERRIER              
Due to size variety within the breed, the puppies’ size also varies. In addition, the Boston Terrier puppies grow with differences, and while most grow gradually, others have fast growth periods. Puppies that grow that fast can end up uneven and ugly temporarily and its exercise should be adapted to prevent injuries, and what it is most important, avoid the puppy’s frustration.

Adult size is usually reached after a year, although males continue developing more substance. Ear and tail cropping is optional in the breed, and is not encouraged. Ear cropping will only be done if the ears are large, rounded or not erect (attention to each country’s current bans). Breeders don’t crop the ears until the dog is six months old. Socializing should be done diligently, especially on males, to avoid a bully character and antisocial behavior. Obedience training is recommended from early age.
The puppy’s eyes are vulnerable and prone to injury by scratching or rough play. Breeders and owners should watch these and other eye problems, such as glaucoma, distichiasis and crossed eyes.
A good partner in general, the Boston Terrier is an easy to care for dog that grows attached to its owner. It is an excellent guardian.
Although the Boston Terrier’s potential problems might scare the new owner, the breed in general is very resistant and long-lived. The Boston Terrier suffers many congenital and hereditary problems, including heart defects, deafness and juvenile cataracts. In addition, hydrocephalic cases have been reported (liquid in the brain cavity), sea lion puppies (seriously bloated, deformed puppies) and with the swimming puppy syndrome (anomaly in which the puppy is unable to stand). Incorrect bites, straight hocks, kneecap dislocation, cherry eye, hyperadrenocorticism, and poor vertebral growth. Malign and benign tumors and cysts are also frequent in older dogs. Some Boston Terriers have a poor reaction to anesthesia. Due to its brachycephalic muzzle, the Boston is prone to heat stroke and sinus problems. Care is minimal, and exercise can be satisfied with regular training and daily walks. The Boston Terrier lives between 12 and 15 years.
