Jinxx is loosing his baby teeth and is teething. He is chewing on everything he can get his teeth onto. This includes our other horse. He keeps nipping at her and will not leave her alone. I don't want to keep him in his stall all the time time, but I also don't want him biting at Angel constantly and leaving sores. I have a jug with a bunch of rocks tied to the rail for him to chew on and he does play with it from time to time. I also have a jolly ball and and big inflatable ball for him, but he shows no interest in them. Does anyone have any ideas of what I can do?
