Preston has a problem with his male American Bulldog:
“I have a 2 year old American Bull Dog. He’s very socialized with other dogs. The only problem he has is that he will show aggression to another male dog that is not neutered. Why is that.”
If your dog has not himself been neutered, then he is most likely reacting to the male hormones. He will see the other dogs as competition or a threat. Think about having him neutered if you do not intend using him for breeding or showing.
