If you don’t have good results within a reasonable amount of time, or the symptoms have been going on for 1 year/ 4 seasons without significant relief or the symptoms are severe.
I would ask for a referral to a veterinary dermatologist. There is a BIG difference between a regular veterinarian and a veterinary specialist.
PS: I went back and forth for a year, tried more than one vet with poor results regarding my dog with allergies.
Got positive results after 1 visit with a veterinary dermatologist.
