How many licks does it take to get through a Filled Bone? We don’t know for sure, but we are confident your power chewer will lather you with kisses for treating them to a Redbarn Filled Bone. One of our most popular treats, we take all-natural white beef femur bones and stuff them with a delectable filling. It’s the perfect pairing of taste and health, as chewing is a natural boredom-buster, stress-reliever, and plaque-remover for your dog. Once the filling is licked away, feel free to keep the bone and refill with your own fillings, like peanut butter from the pantry!
