Try the breeder referral service on
www.bostonterrierclubofamerica.org. All the breeders are not the best, so only look at those that do OFA, CERF and BAER testing. Be prepared to spend some money with a reputable breeder, and you will save money in the end. Please do not go to Craigslist, or any other classifieds. You may try rescue as occassionally, they do rescue puppies. Good Luck!
