Natural beef femur bone with highly palatable fillings. No grains or rawhide! | Satisfies their natural instinct to chew for the perfect pairing of health and taste. These natural dog dental bone chews help to remove harmful plaque and tartar supporting overall dental health. | 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. | Chewing is a natural boredom-buster, stress-reliever, and plaque-remover for your dog. This durable, long-lasting treat will keep your power chewer busy! | Safety is our top priority. Our in-house quality assurance team performs more than 2,500 tests per month. Our white bones are natural beef femur bones sourced from grass-fed cattle. Cleaned and cooked in our company-owned Kansas facility, each bone is naturally cleaned without the use of bleach or harsh chemicals and baked in ovens for increased safety and durability.
