There are some dogs that have either an allergy to specific grains or simply dietary intolerance to specific grains. One of IdlePaw's dogs, Oswald, is one of those. He does much better with a grain fee diet and is not the only pup out there with an issue. Fortunately, peanuts are not a grain and dogs LOVE peanut butter. IdlePaw's mixes this batch up with grain free flours to create all natural tasty, crunchy treat that any dog will enjoy, whether they are on a grain free diet or not. Cookies are cut into 1" heart shapes and can be broken easily if needed.
