We take concerns about nut allergies seriously. While our kibble manufacturers do not buy any peanuts or peanut-based ingredients, we cannot guarantee that individual ingredients don't contain peanut or tree-nut residue of some kind, as they are processed in other facilities, separate from the pet food maker. Thus, even though we do not use nuts in our recipes, we cannot absolutely guarantee that no nut has come into contact with an ingredient at some point.
We do use peanut butter as an ingredient in our baked dog treats, so you'll want to avoid those.
