For instance, if your dog was on a grain-free chicken diet, look for another food offering chicken and no grains. You don't necessarily need to find a food with the same exact ingredients, but if you find one that has at least the same first ingredients, you may be better off than a dog food with totally different meat sources and containing grains.

Pamper the Gut
