Made of fibrous keratin rather than bone, great for cleaning teeth and won't become sticky or slimy upon chewing. Long-lasting and durable, Anco Goat Horns are much less likely to splinter than processed bones as chewing grinds the horn down slowly. They satisfy your dog's natural urge to chew and provides a safe and tasty outlet for bored/stressed dogs, while also being a healthy treat at only 3% fat content!
