If you get a Boston from a reputable breeder, they should be fine. Mine just turned 6 and has had no health problems (aside from the odd accident related leg/foot problem). He normally has his mouth closed and breathes through his nose unless he's working hard.
Bostons and Frenchies share similar ancestries. How are Bostons for breeding? Do they need artificial insemination and c-sections like Frenchies normally do?
Not sure about C-sections, actually. I think I remember the breeder I got Ziggy from saying that they had sent their males away to breed with other females though, which would imply natural insemination I guess.
