all has been fine...then yesterday Ham had to go out, we walked, he did a bowel movement..we came in. THEN he kept licking his behind...ok, at first I thought it was a cleaning thing....but he started to seem agitated. I lifted his tail and there seems to be an irritation right at the base of his tail...not really his little bottom, but from it up about an inch at tail base. I see a redness. Needless to say, I poured over him looking for fleas, etc. I see nothing (I know, doesn't mean nothing is there) When he was calm, I put Neosporin on it, then didn't allow him to bother it. It seemed to ease his discomfort immediately. Any ideas???? Seems to have come about suddenly. I put more Neosporin on again this morning...he seems calmer about it, but the redness is still there. Thanks.
