I have 2 BC sisters, 7 months old. They play fight with each other alot. snapping, play biting, wrestling, etc. I have started taking them separately with me on the farm on my side by side to work on obedience training. I have noticed the last two times that they both got on the seat with me, they got into a more vicious type of fight. One dog cowered and didn't want to get back up on the seat. I feel like this could be a domain/jealousy issue. These 2 will be expected to work stock together with me, so I'm a little concerned with this behavior. Any thoughts or suggestions please?
