Two things I can address. One I would use Petflow.com. I live in a small town and it is great, mostly quality food, cheaper than I could buy at a store. If you are looking at Canadian made Orijen and Arcadia are absolutely the best. They use locally sourced food.
The allergy, I would spend the money and use a dermatologist. My Bernese started itching. I opted to take her to a dermatologist. Based on what I told him, without doing testing, he said it was a type of mange (she had no hair loss or bald patches) He gave me mediation and all dogs had to get it. My vet wasn’t happy that I opted for a dermatologist and said it was allergies. One month later Molly was itch free and has been since that time. My vet had to eat crow. What is very important to the dermatologist is information, when did it start any thing new or unusual. It could also be something as simple as a year of bad pollen.
Good luck. Pam
