We love our original Filled Bones, but as a company committed to continuous improvement and innovation, we wanted to create a line of Natural Filled Bones equally beloved by Redbarn dogs. Just like their original counterparts, our Natural Filled Bones are made from thick, durable, and smooth beef femur bones, naturally cleaned without the use of bleach or other harsh chemicals. 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 Filled Bones help support your dog’s mental and Dental healthy by acting as natural boredom-busters, stress-relievers, and plaque-removers.
