Profile description
The Boston Terrier is a small, compact companion breed developed in the United States from bull-and-terrier-type dogs. Most adults stand around 38 to 43 centimetres tall and weigh approximately 7 to 11 kilograms, although recognised weight categories may vary. The breed has a square body, short muzzle, large erect ears and prominent round eyes. Its short coat is normally brindle, black or seal with clearly defined white markings, creating the formal appearance that led to the nickname “American Gentleman.” Boston Terriers are usually affectionate, sociable, lively and highly people-oriented.
They commonly enjoy family life and can adapt well to apartments, older owners and households with children when treated respectfully. They are intelligent and often entertaining, with expressive behaviour and a playful nature. Most enjoy learning with positive reinforcement, although some can be stubborn or easily distracted. The shortened skull shape can produce snoring, noisy breathing, heat intolerance and other airway difficulties.
Their prominent eyes are also vulnerable to injury, dryness and ulceration. Boston Terriers are generally friendly with people and other animals when properly socialised, but individual personalities vary. Their compact size should not lead owners to assume they require no exercise or training. This breed generally suits owners who can provide companionship, moderate daily activity, careful weight control and close attention to breathing, eye and heat-related health concerns. The Boston terrier's typical affectionate, gentle, intelligent qualities are most constructive when household rules are predictable and desirable behaviour receives regular reinforcement.
Choosing a Boston terrier should involve considering the whole adult dog rather than appearance alone. A prospective Boston terrier owner should plan for a moderate activity commitment and short-coat maintenance, while allowing for the breed's affectionate and gentle manner.

Care requirements
The Boston terrier requires moderate daily exercise, careful heat management and regular monitoring of its eyes, breathing and body weight. Several short walks and play sessions are usually more appropriate than prolonged strenuous exercise. Activity should be reduced during hot, humid weather, and the dog should never be left in a hot vehicle or exercised heavily during the warmest part of the day.
A harness is often preferable to a collar because it reduces pressure on the throat, although it must fit without restricting the shoulders. Training should begin early and use positive reinforcement, short sessions and consistent household rules. Toilet training may require patience. Socialisation should include people, children, friendly dogs, traffic, household noises and veterinary handling.
The short coat requires weekly brushing and occasional bathing. Facial folds should be kept clean and dry.
The prominent eyes should be checked daily for redness, cloudiness, squinting, discharge or injury, and urgent veterinary care is required for signs of eye pain. Teeth should be brushed frequently because crowding can increase dental disease. Nails should be trimmed regularly and ears checked for wax or infection. Food portions should be measured carefully because obesity worsens breathing problems and stresses the joints. Regular veterinary examinations should monitor the airways, heart, knees, spine, eyes, skin and dental health. Owners should discuss the risks of anaesthesia and breathing complications with their veterinarian. Swimming should be closely supervised because the breed’s body shape and shortened muzzle may make it a poor swimmer. Owners should establish the Boston terrier's normal appetite, breathing, movement, sleep and social behaviour so a persistent departure from that baseline can be investigated promptly. Care requirements for a senior Boston terrier should be reviewed as mobility, senses and recovery change; shorter sessions, better footing and easier access can preserve independence without removing enrichment.
