The Redbarn White All-Natural Beef Femur Dog Bones are one of our most popular dog treats. We take white, all-natural 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.
