I only feed my dogs grain free food with fish oil supplement. Dogs don't eat cereal. Purina is cereal. IAMS. Corn main thing that causes itching. I feed taste of the wild. You pay the vet or give them the food that they were meant to eat. Meat based. I buy the fish oil from Costco. I give the dogs joint supplements if they are active in the field. None of my dogs have any health issues.
where is the dog licking at again? the licking can produce a lick granuloma which are a pain to treat. there are different types of boots that can be put on. dressings with duck tape. why do you think your dog is licking? there are other reasons other than food. anxiety, thyroid, boredom, etc.
