So this was one of the rescued CP's I took in a while ago, I'm not sure if this was a recent or previous injury but I never seen it before. We recently took off some stuck shed on her, she was blue when I got her and her shed retained completely, I had to soak her and take it off myself and it came off really easily in one piece.
Anyway, here's the injury. Seems like a ripped belly scale to me, was thinking a betadine soak or polysporin?
