Canine Butcher Shop Premium Rawhide Grillers SINGLE INGREDIENT. For more than 20 years, we have used ZERO additives (no salt, sugar, flavors, coloring, or preservatives) in all our products, where they are always processed in our dedicated facility in Chicago, IL. While other brands share sources, our materials are locally sourced from human snack food production and batched-tested for quality in our USDA approved facility. UNIQUE PRODUCT. The only grillers on the market that are Truly Grilled. We grill at 800 degrees Fahrenheit, which locks-in the most flavor and leaves real grill marks. Beef Collagen. Rawhide grillers are made of beef collagen, an essential protein for mammals, that strengthens teeth, bones, joints, nails and hair, and ligaments and tendons. 12 oz resealable, stay-fresh bag. Our cuts are dried to perfection with just the right amount of moisture, to ensure they are not consumed too quickly and will not shatter or snap. The benefit of using thicker cuts is the additional time for needed for your dog to moisten and break down the chew.
