They sell something called blu-kote. It comes in a white bottle with a yellow label that has red writing on it. It's an anti septic wound dressing that you just spray on and it helps stop irritation so that the wound can heal quicker. Maybe if it's not irritating him he won't bite it. You can order it online too. Might be worth checking out.
Cone won't work he's a pit he tears them off
You can get a cone too keep it from biting wound not sure about. Antibiotics for wound .
Grannicks Bitter Apple is the best thing I have ever found for it. Unfortunately TCS doesn't sell it, nothing I ever got from there would deter my dog.
