You can always ease them into a 5 star food too by going with something that is slightly better than what you’re feeding now but not being drastically different. If you’re feeding a 1-star food, go with a 3 or 4 star grain-inclusive food, then maybe a 4-4.5 star grain free food, then try a couple 5 star foods. I actually feed 4.5 and 5 star foods. I do keep a grain-inclusive food in my rotation but it is gluten free (Nutrisource small/med breed puppy, Nature’s Logic and sometimes Nature’s Select Hi-Pro). Basically, I avoid wheat, rye, barley (gluten grains). Barley is easily contaminated with other gluten grains during processing at the plant. Rice, millet and quinoa are gluten free. This is just one way to transition to a better food. If they get digestive upset, then don’t increase the new food amount until they are regular. Transitioning can be quick or take weeks or months.
