Hi Brie,
I’ve had dogs that develop allergies to certain protein in food with similar symptoms. While checking in with your vet is a good idea, especially to take care of the ear infections, I don’t think you have to rush to a dermatologist unless there’s no improvement after doing an elimination diet and/or if you don’t see a change from the switch in food.
You need to make sure ALL treats are grain free as well and it’s best to feed everything using the same protein as the food. So you need to use fish based treats. Limited ingredient diets are good if you don’t get great improvement on the current food. I do use Kefir as a probiotic since it helps control yeast. Good luck!
