I have read somewhere that licking the other dogs mouth is a sign of submission. The biting at the other ones legs seems to me like he is just wanting to play. So it's as if he is saying, please don't be mad at me, but I just want to play. I'm surprised that the older dog tolerates it so well.
I agree with the others, separate them for part of the day, or provide a crate for the older dog to go into when he wants some relief from the young tyrant. |
