For best results, consult a veterinary dermatologist. Get the dog properly diagnosed first, then you can evaluate your diet and treatment options.
By any chance was this a pet shop/puppy mill dog? Because a lot of breeders continue to breed dogs that have environmental allergies even though they shouldn’t. There is a genetic link.
I have an allergic dog, she is doing very well under the care of a veterinary dermatologist, sees him once a year. It’s all good. And, she tolerates a variety of foods, but does best on Nutrisca Salmon and Chickpea
Raw made her sick, emergency vet visits and all.
