Frequently asked questions

How much does a Boston Terrier cost?
Expect roughly $1,000-$2,500 from a reputable US breeder, with some lines priced higher. The purchase is only the start: as a short-muzzled breed, it can run up real bills for airway, eye, and knee problems over its life, so budgeting for insurance or a dedicated vet fund is wise. Lifetime costs including food, routine care, and the occasional surgery add up to far more than the sticker price.
What is a Boston Terrier's temperament like?
Friendly, upbeat, and people-focused, the Boston Terrier is one of the more even-tempered small breeds. It is playful without being frantic, trains readily with consistent handling, and is rarely aggressive. Most enjoy being close to their people and adapt well to family and apartment life.
Can a Boston Terrier be left alone while I work?
An adult usually manages around half a workday once it has been built up to it gradually. The breed is quite people-oriented, so long full days alone every day can lead to boredom and mild separation stress. If the house is empty from morning to night, plan for a midday visit or a different arrangement.
Is a Boston Terrier good with kids?
Yes, it is a good family dog with basic rules in place. It is sturdy enough for gentle play and generally patient, but its prominent eyes and short airway mean kids should learn not to poke, wrestle roughly, or over-excite it, especially in warm weather.
