So, today we were on our way home from our ride when one of my two dogs got in front of Andy. Usually he just gives them a warning and they move out of the way. But today she (the dog) didn't move so he got mad, pinned his ears back and tried to hit her with his front hooves, rearing up a little and gave a few small bucks. I was totally unprepared but stayed on.
By this time she was walking behind him and he went right back to normal and calmly walked home like nothing happened. Any tips for what I should do when he does this and how to get him use to not being in front all the time? He and dogs get along fine normally. Any advice is greatly appreciated.
