I have a 1 year old male bulldog. He was neutered at about 8 months old. He is highly aggressive towards people including myself. He has bitten several times. I can't even relax on the couch without him lunging at me. I am not sure if this is the puppy phase? Or if this dog has serious aggression issues. If I put him outside he starts to eat the siding of my house and the framing outside the door and constantly barks until I let him in. I adopted him from an animal shelter and thought he was really sweet but the more comfortable he has gotten at my home.. the more aggressive he's gotten. Any recommendations on how to deal with these issues? I eventually plan on having a kid.... and I cannot have an aggressive dog like this running around my home. Any advice would be much appreciated.
