“He has been to 3 different vets in my area and they all either just want him to stay on benadryl or give him steroid injections”.
Just wanted to add my 2 cents, while you are waiting for Marie to respond.
Sometimes steroids are necessary (temporarily) to stop the suffering and risk of infection until an accurate diagnosis is made. Sounds like it could be environmental allergies which are unrelated to food.
Has your vet referred you to a veterinary dermatologist? That is where I would start.
