It's not infected, nor it's bleeding, but the skin was visible. With the remaining spray medication, the vet told us to cover the area once a day to help its healing. This medicine acts as cortex sweller, so it has built a cortex of dry blood, or scar, but eventually has to heal from the inside up, he said.
After reading some blogs and asked relatives about the case, it seems the healing process is somewhat procedure, but it doesn't look good to me. I may look for a second professional opinion this week. Thanks.
If I am right about the area you are describing, there isn't much skin to stretch in that area. Did your Vet indicate it will have to heal from the inside? Does it look infected or is it bleeding? I would call the Vet first that did the procedure and ask if this is the normal expected healing process in this area. We're you instructed to keep any salve or medication on it?
If you aren't happy with that follow up, then seek another opinion.
