Never heard of it so I read up on it.
I don't think I've ever had one with it. Though I did recently have my silkie/giant with frozen poop crusty butt. Took the scissors to her and did some major hacking, never seen such a poofy fluffy butt, it was like goose down once I got the frozen hunk off. She doesn't have silkie feathering but boy her butt was fluffy.
I'm sure you've already researched it but have you thought of trying Gentian violet?
I know that's what the doctor prescribed when one of our kids got thrush mouth from either long term strong antibiotics or maybe it was from one of the asthma medicines they were trying on her, don't remember, was awhile ago.
Hmm, reading up on gentian violet guess it's in blu kote.
Gentian violet's a new one for me. I'm going to have to look into that. Thanks!
