I would say that it does not seem unusual for a puppy to be humping anything or anyone be it dog, human, or toy. My guess is he is just playing. Whether or not I'd leave them alone all day depends on how persistent he is and if he is hurting or really bothering the other puppy. In the meantime you might try "training" him to leave her alone by removing him from her when you see the action and give him something else to play with to take him mind off of her. Maybe also, remove him, give him a toy, then give him a treat and tell him he is a good boy. I'm no expert, but that is what I would try. |
