We have a very sweet American Bulldog/Staffordshire terrier named Jack who we are looking to rehome. He is 7 1/2 years old, around 80 pounds, neutered and up to date on his shots. We have had him since he was 3 months old. He was bottle fed from 4 days old because his mother, who was rescued, wasn't able to feed the puppies. Because of this he is a real loveable guy. We used to have another dog, a female pitbull/boxer that he would wrestle with all the time when he was younger. He has never shown any aggression, which is why he was able to get along with her. She would boss him around and hump his head and he was ok with that. He would likely be fine if you have another large dog, though we'd want them to meet and be sure. He ignores my parent's Sheltie when they visit. I don't think he would make a good companion for a small dog. He isn't much of a barker and never whines. He loves anyone who comes over and wants to make them his best friend. He does alert us to strangers arriving.
