Opps forgot to mention, the last time this happen I had pip looked over. My vet said that he was just reacting to the greenies. To just keep water down him, and it would clear up on it's own. It wasn't bad or anything, other then his slight discharge. And the horriable smell he had to his pee. So what could be in greenies that I have to avoid with other products I feed them? The new product I started them on was Missing Link. So if that is out, what can I feed them to help them with their coats?
