I hate to give an answer that may not be much help, but I must tell you how glad I am that you are giving a rescue dog a second chance. I hope you are working with a good rescue that will be sure to make a successful placement. Maybe your rescue would be the best place to find out about a good book. Pet stores are terrible place to buy a dog, but maybe a good place to buy a book. I frequently see displays of books covering many different breeds. If all else fails, there is Amazon.

Hi labman, they seem to be a good rescue organization. Right now I'm waiting for my application to be approved, which includes talking to my vet and a home visit. The lady I'm working with is asking all kinds of questions as to what I'm looking for in a BT. I've used Amazon for a book, which is very general, although it has great pics of the Bostons. I will ask the rescue lady if she can recommend a good book on BT's. Thanks for the suggestion. Susan
