About the Boston Terrier

The Boston Terrier is a small companion dog developed in the United States, originating in Boston in the nineteenth century. It has a compact, square build, a short flat muzzle, large upright ears and a smooth, short coat that is often brindle, seal or black with white markings. It is now a friendly, sociable pet and is often described as the American gentleman of the dog world.

Temperament

Typically friendly, lively and affectionate, with a clownish streak. It usually enjoys people and attention, can be sensitive and sometimes stubborn, and generally adapts well to different homes.

Exercise

Needs a couple of short to moderate walks and play each day. Avoid strenuous exercise in hot or humid weather because of its short muzzle.

Grooming

The fine, short coat needs only a weekly rub with a soft brush. Wipe the dark, prominent eyes and any creases around the flat muzzle with a damp cloth.

Care & wellbeing

Flat-faced dogs are sensitive to heat and may snore or struggle in hot weather. Keep weight healthy, protect the prominent eyes from injury and ask a vet about breed-appropriate breathing and eye checks.

  • Little or no professional grooming needed

A relative guide, not a price — costs vary a lot by country, insurer and lifestyle.

Is a Boston Terrier right for you?

Could suit

  • Owners who can manage a good walk or two each day
  • People who'd rather not spend much time grooming
  • Smaller homes, as long as daily exercise needs are met

Think twice if

  • You live somewhere hot or want a very active companion — flat-faced breeds can struggle with breathing and heat
