The WHIMZEES Rice Bone Dental Dog Chews are a perfect, all-natural vegetarian treat designed to keep your dog busy and promote dental hygiene. These easily digestible chews are low in fat and contain no artificial colors, flavors, preservatives, GMOs, or meat. The firm shape encourages gradual gnawing, helping to freshen breath and reduce plaque and tartar buildup on your dog's teeth. Studies show WHIMZEES are highly effective at reducing plaque and offer a longer chew time. More fibers help polish teeth for an even longer-lasting chew. These chews are gluten-free and aid in improving metabolism and muscle tone, while promoting strong bones and a healthy shiny coat.
