Ripley is a pest. Dakota is pretty tolerant of him, but when Ripley starts getting in his face, he will bare his front teeth and growl softly. Tonight, while I was working with the two, Ripley started jumping and yapping in an attempt to get a treat. Dakota started doing the lip curl and I distracted him with a down command. Ripley bounced right on top of Dakota, and Dakota just silently snapped at Ripley. He didn't touch him, but I got between the two of them before Ripley could react aggressively and further irritate Dakota. I know the two of them are having some "male conflict" issues, neither one really likes the other and Ripley does need to learn to give Dakota some space. If Ripley was bigger, I would let the two of them sort out their own space issues. But, I worry that because Ripley is so tiny (Dakota is 10 times his size) Dakota could hurt him without meaning to. What would you do here? I really am hesitant to allow the two to bicker simply because of the size difference, but I am not sure how else to teach Ripley that it is not safe to walk all over Dakota. Normally I keep the two separated, but in the RV that isn't possible and I need them to live as harmoniously as they can. Any tips/suggestions are appreciated!
