4Health has four official ranges of kibble — Original, Grain-Free, Untamed, and Special Care. Obviously, the Grain-Free products are totally gluten-free and contain zero grains. That means no rice or oatmeal, either.
However, there are also grain-free kibbles within the Special Care and Untamed lines of 4Health dog food, like the Sensitive Stomach option in our 4Health reviews above. What we can’t ever assure anyone is that a dog food will be free from cross-contamination. As 4Health, like so many other brands, is manufactured at a larger plant that produces other dog foods, it’s important to keep in mind that the facilities may sometimes be used to handle grain ingredients.
