So at least half of this big scab ripped off and was hanging there like a tag on the back of your shirt. I cut it off, and now there's a smaller area of pink/white fragile skin that needs protected. I have called the vet and asked for a prescription for Silvadene. I can use that on both my bunnies. They don't have in in stock but I could order it online and then they call to verify the prescription. This vet office is probably sick of me, but it's the only local clinic.
