I understand, my little dog was the same. At age 4 we ended up at the emergency vet times 2, then a veterinary dermatologist (we didn’t like him).
We tried another veterinary dermatologist (within a week of seeing the first one) with excellent results.
BTW: Dogs do not develop allergies from eating the same foods day after day.
RIDICULOUS! My dog now eats chicken almost every day!

PS: Allergies get worse with age, not better.
You may want to notify the breeder (if you know) it’s a hereditary condition, best not to breed this dog.
Good luck
