I kept in close contact with my vet, and sent her photos every couple of days. Mostly, there had to be good granulation in the wound before we would even consider to stop bandaging it.
The longer you keep it bandaged, the less it will scar. So I kept Red bandaged pretty long and it doesn't look like he's going to have much of a scar, because it is healing nice.
I never noticed him trying to nibble at it or scratch at it. Granted, based on its location, it would have been hard for him to stand on 3 legs and reach around the chew on it!!! So that wasn't a problem.
Really the only issue we are left with is now he is a booger at lifting that leg to let me pick out his feet. We had a mini "come-to-Jesus" about that last night, and he at least stood still, and picked it up quickly, and put it back down without trying to fall over. Baby steps.....
