Benebones are made with USA-sourced nylon and flavored with USA-sourced real ingredients – real peanuts, white meat chicken, or bacon. That’s it! We like to keep it simple. Note that because all of our products are made in a factory where nuts are used, avoid introducing any Benebone product in a household with an allergy to nuts of any kind, pork, chicken or nylon. Made with peanut butter. For dogs under 30 lbs.
