“I didn’t know there were dermatologists for dogs. I wonder if I can just go see one instead of a vet? They might know more than a vet would maybe”?

Yes, you can, and I was going to suggest that. What area are you in (state)? You can call the nearest veterinary school, often they have specialists or will know where to refer you.
Bring whatever records you have, negative heartworm test if you have it, proof of last rabies ( the only vaccination required by law). The only thing is…if they think the dog needs some lab work to rule out medical issues….but they probably have regular vets there too. Has the dog seen a vet in the last couple of years?

I wouldn’t worry too much about the food right now, the skin condition/allergies might not even be related to it. I would make seeing the dermatologist the #1 priority. One thing at a time.

I understand where your uncle is coming from, some dogs do okay on a low quality food, but some don’t. See what the vet says. Paying more doesn’t always mean it’s better!

PS: I’d rather be an outdoor dog instead of an indoor dog that was crated all day 😉
