Marceau is a sweet boy who will do best as an only dog. While he has gotten along with my two large female dogs, he is strong and rough when playing with them. He has a strong drive to disable them and while he hasn't caused injury, he certainly has come close and caused them to cry out. With cats, he will chase, corner and again, try to disable. We were not aware of this when we adopted. The trait was not so strong the first few months but became quite strong as time progressed and he became comfortable in our home. He is a very sweet companion and loves to cuddle and be close. He can be jealous of other pets receiving attention by muscling them away from the person. This is why I believe he will be best as the only pet. He is very smart and quite trainable as we have taught him some hand signals such as sit, come, kennel up, stop, down and no. Yes, he is deaf, but very in tune with your body and facial expressions. He is totally housebroken, kennel trained, and does not chew on furniture but will steal socks and paper napkins. He loves to eat and is an over exuberant treat eater. We are successfully working on taking treats with a soft mouth. He also is beginning to slow down at eating. Marceau loves walks and behaves comfortably on the leash when wearing his harness...he does not pull. When strangers reach out to pet him tho, he is very submissive and sinks down. We do not hit, but I think he may have been handled roughly before coming to us. I am heartbroken to be rehoming him, but we have several cats and two other dogs and running interference between the pets constantly is exhausting. Also, he is very muscular as American Bulldogs are, and I am always watchful and cautious around children. He is on leash in the house at all times so that no one gets hurt . I am hopeful for a placement that he can have one on one training and relationship with his very own human.
