Our dog can't stand me and OH hugging. If he catches us out he'd jump up on me and try to direct me away from OH. I assume he thinks it's a kind of aggression as he does the same thing when we're arguing about something. As soon as we raise our voices he'd go for me, trying to separate me from OH as far as possible. Always me! Equally if I pet another dog... same thing.
I don't really understand why he does it. Is he trying to protect OH from the me - the meanie?? And do I need to worry about it? I have to say that he is fairly effective though and manages to break up fights in our house very quickly. We haven't been arguing much lately. We haven't been hugging much either
