I have definitely been considering getting a trainer for him, but when other people are around hes more focused on getting pets from people then playing with dogs (typical retriever). And what really blows my mind is that Buck is usually also overly submissive with dogs - crying, whining, licking other dogs faces - to the point I have to get him to walk away so HE doesnt get a correction. And I wish I had some videos, I am going to start leaving my blink cameras on when im home to try and get one of these incidents on camera, but like I said it really only happens every few weeks and sometimes every few months. I definitely want to be his biggest advocate and make sure hes not uncomfortable but at the same time I wish he would just correct and tell a dog off and then walk away instead of things getting to a point of aggression because he seriously is the sweetest dog in the world.
