I would try NutriSource. I’ve read that dogs transition to it easily. I would also add some probiotics & digestive enzymes. I’d say do a slow transition and you can, IF the rescue can tell you exactly what food he was on, you can then buy the smallest bag. If not, do what you have to. Regarding probiotics & enzymes, go to a pet store and buy whist they have, so you don’t have to order online & wait.
