I have heard of alot of people using something called Chris Christianson, (or CC System) I think that's the name. They all rave about it. I currently use fluffy puppy by Biogroom. t seems to be o.k. and smells pretty nice.
Hi there, I'm new here and just saw your post. One thing I thought of....if your pup is on pain meds maybe they are upsetting his stomach and causing overall irritation. This happened to my yorkie when he got neutered.
