I have a Boston Terrier and many firends in rescue. I would not want to encourage someone looking for a Christmas pet persay. However here are some links to some great rescues, many of the wonderful volunteers are my friends. You can get great information from the sites below on whether one wouldbe a good fit. I love them and are very hooked. I am now waiting on a one girl to be finished with her show career and hopefully she will be joining our family.

http://www.abtr.net/index.html One of the best rescues in the nation. They have volunteers all over and can arrange transport for the right family.
http://www.dallasbts.com/ A wonderful meet up group for the dallas area. I have been a member for 4 years. we have a meet up once a month here in Plano, check out the dates and times, you can come by and meet us and get some wonderful advice on owning a Boston.
Please research the breed carefully. While I do not trust mone with babies, he is way rambunctuos. But he was not raised with them either. The rescue groups should all have links to Breed clubs where you can get info on great breeders. However there are usually waiting lists as they usually have very small liters. You do not want to look for a dog for christmas but a breeder with ethics, that does not over breed and puts the bitches health first.
