13 yr JRT snaps at owners.
I have a 13 yr old male JRT. He is on Hapato Support pills for an elevated liver count. In the last few months, sometimes when we go to pet him he will run away or try to bite us. When he snaps at us he runs away and hides under the bed like he knew he did something bad. We have stopped putting our face near his and giving him kisses as he might bite us. We love our JRT very much and want to know how to stop this behaviour.
