Red Barn Dur-A-Bulls Bone Rawhide-Free Hikory Barbecue Flavor Hard Chew Dog Treats are available in both Medium and Large bone-shaped dog chews made to satisfy strong chewers with a completely digestible recipe. These Dur-a-Bulls bones have the look of a typical dog bone but are formed from Redbarn’s unique blend of natural ingredients (including real collagen from beef) and cooked to have a hard, long-lasting consistency. Each bone is enriched with a hickory BBQ flavor that dogs can’t resist, keeping them interested in chewing. They’re a great alternative to nylon or plastic bones, as every bit of these bones can be chewed and swallowed safely. With only seven ingredients and no rawhide, they offer dogs a fun chewing challenge and help scrape plaque off teeth while avoiding the digestive issues that rawhide or synthetic chews might cause. Available in Multiple Sizes and Pack Options
