I've had zero issues with Kirkland Grain Free dog food from Costco. It costs about $1/pound give or take depending on the protein source (they offer Salmon, Turkey, and Beef). The carbohydrate source is from sweet potato. I've used this site and their deep analyses to understand what is optimal (according to them): https://www.dogfoodadvisor.com/dog-food-reviews/natures-domain-dog-food/ https://www.dogfoodadvisor.com/dog-food-reviews/natures-doma.... They also have a newsletter that emails whenever a recall of dog food/snacks is initiated. Both of my dogs (smallish breeds) have been able to switch between with minimal effort to transition all that slowly, and their weight has been stable/healthy despite not nearly enough physical activity.
