2-year old Lab doesn’t understand dog/cat personal space
I have a 2 year old male who is plainly just obnoxious to other dogs. He just doesn’t get it when other dogs don’t want to play with him. He’s obviously dominant as well as he will stand over them and/or circle mercilessly- obviously we make him stop. But how do we teach him about doggy etiquette? I have 2 other Labs who are older and just don’t ever tell him off. He had an elbow injury and surgery when he was 5 months old, which kept him away from the other dogs for some months, so I’m assuming that is part of his obsession with other dogs. Looking for suggestions!
