My 1 year old shiba keeps licking at his butt hole! I know it sounds kinda weird but at first I thought he was just chasing his tail, but the whole time he was trying to get to hie butt whole and once he did, he hasn't non-stop licking his butt for the last hour! IM worried it will last longer and I have a upcoming party at my house .What does this mean and how can I make him quit it, its disgusting and embarassing with people over.
