Hi,I have a BT puppy that is 3 months old, Amos. This is not my first Boston, we lost our 7 year old a year ago to a brain tumor that caused him to go blind. Wilson was a wonderful good looking dog. 27 pounds of pure muscle. Amos is adorable and seems to be on the large size. He has big paws. Took him to the vet today, he is 15 pounds at 3 months old. I don’t remember how much Wilson weighed at this age. Wondering how big he is going to be. I also have a 3/4 rat terrier, 1/4 Boston mix that is 10 pounds. She is Talulah aka LuLu.
