Poor Baxter. It sounds like he is suffering from an allergy or a skin infection. You can try to give Benadryl twice a day for the itchiness but I would contact your vet for an accurate dose dependent on your dogs weight and age. I would also put a cone collar on him to prevent the licking. If he doesn't stop licking it will not improve. Finally, since it is so raw, I would have your vet take a look at it to see if he needs some oral antibiotics and stronger allergy meds to help him heal faster. I hope this helps!
