Jeeves, 14 month old blue roan and tan boy, has recently started the rather annoying habit of chewing on his tail, or one of his ears (doesn't matter which one - whichever he can grab hold of). He was neutered about two months ago, but this behavior is only recent. I'm a bit worried he will end up eating himself, (I know that is not physically possible - but it seems that what his intention is) or at the very least have an ugly looking tail. He is washed every Sunday and I ensure that there is no shampoo left on him anywhere, rinsing him until the water runs clear. He has been groomed and the feathering around his ears has been cut. Is this tail/ear chewing normal?
