I come from a Boston Terrier family. In fact, my mom just got the newest Boston in December. His name is Mr. Darcy and he is a precious, energetic little dog. He is a compact little fellow, and has a good bit of brindle in his coat. He is very handsome and loves my dad to death.
I don't think they cost nearly that much here, but I have forwarded your message to Mom for some input.
I know that the English Bulldog runs in excess of $1,000 because of breeding problems. But I have no idea why a Boston would be so expensive. Maybe its because there are a lack of Breeders.
