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. Our filled bone manufacturing process is a unique blend of state-of-the-art technology and handcrafted quality. First, the all-natural beef femur bones are bathed in industrial steel vats, allowing the bones to naturally clean themselves. Then, they're oven-roasted for maximum safety. Finally, we hand fill every bone through a proprietary process, allowing our original filled bones to stay semi-moist and perfectly placed, adhering to bone walls instead of carpets.
