I have had Romeo, my white silkie roo, for about 1 year now. I do not know how old he was when I got him. He has always kept himself looking tip-top shape for his ladies. The last week and a half, he has had a very nasty vent area that goes all the way down his backside. I had fed some veggies and watermelon so I though that was the cause, but it hasn't gotten better, and he won't clean it like usual. He seems to be doing everything else normal, eating, drinking, caring for his ladies, etc. Do you thing something is wrong with him? Should I bathe him? Please, I'll take any advice. Thanks!!
