The Peanut Butter Flavorit Bone is infused with human-grade peanut butter flavoring, allergen free! You can fill this reusable toy with peanut butter, cheese, cream cheese, or any other spreadable treat your dog prefers. The tiny flavor cells hold just enough spread to lure your dog to chew, without the heavy intake of excess unhealthy calories. Once your dog is done chewing, just run the bone through the top rack of the dishwasher for a thorough cleaning and it’s ready for the next round of chewing! Yum.
