22 lb Crave Adult Dry Dog Food With Protein, Salmon & Ocean Fish, $27.99

This is an excellent price for a good quality dog food, rated 4.5 stars at dogfoodadvisor.com. It was recommended by my vet for my golden retriever with allergies and a sensitive stomach and he's doing really, really well on this food. Note: it is grain free which is causing problems for some dogs, but my vet didn't seem concerned about that. https://www.amazon.com/gp/product/B07281KQCX/
