We've had three Boston Terriers since we've been married.  They are the American Gentleman and are a  non-sporting breed.
Where does the name come from.?  
They originated when Robert Hooper of Boston purchased a dog named Judge that was a mix of Bull and Terrier lineage.
There are a lot of different terriers types in dogs
They are the sweetest dogs, but they can be super stubborn also.  But oh so smart!
They look like they would be sweet. They have breathing problems I thought someone told me.
Their average life pan is 11 to 13 years and yes they can have breathing issues due to their short nose, mostly snoring and snuffling, but nothing that really causes them distress.
That's good. Do they sit up in chairs like a humans, lol,
Boston Terrier
The Boston Terrier is a breed of dog originating in the United States of America. This "American Gentleman" was accepted in 1893 by the American Kennel Club as a non-sporting breed. Color and markings are important when distinguishing this breed to the AKC standard. They should be either black, brindle or seal with white markings. Bostons are small and compact with a short tail and erect ears. The AKC says they are highly intelligent and very easily trained. They are friendly and can be stubborn at
times. The average life span of a Boston is around 11 to 13 years, though some can live well into their teens.
The American Kennel Club ranked the Boston Terrier as the 21st most popular breed in 2016.
