We love our original Filled Bones, but as a company committed to continuous improvement and innovation, we wanted to create a line of Natural Flavor Filled Bones equally beloved by Redbarn dogs. Just like their original counterparts, our Natural Flavor Filled Bones are made from thick, durable, and smooth beef femur bones, gently cleaned without bleach. Then, through a proprietary process, our cooks hand-fill the bones with one of three wholesome, dog-approved fillings. These bones offer a healthy and irresistibly tasty long-lasting chew for the family's Moderate and power chewers. And like all Redbarn bones, Natural Flavor Filled Bones help support your dog's mental and Dental health by acting as natural boredom-busters, stress-relievers, and plaque-removers.
