I switched from Nature’s Variety Instinct (grain-free) to Nature’s Domain since they were both rated 5 stars and the Kirkland’s Nature’s Domain was much cheaper. However, I came back to this site and was checking up on other dog foods and noticed that the Kirkland’s grain free is now rated lower at 3.5 stars. Does anyone know what happened? Is it no longer a good dog food? I stay in the 4-5 star range to make sure my dogs are getting the proper nutrients in their dog food.
