Despite the name, Moon bones aren't actually bones. At Wonderland Of Pets, we offer 100% air dried beef cartilage for your furry friends! A long-lasting chew, low fat and high in protein which is softer and more flexible than bone, it also won't splinter. Cartilage is naturally full of Glucosamine and Chondroitin which are fantastic for keeping joints healthy! Plus, it works as a great 'natural toothbrush,' cleaning teeth naturally. Your furry friend will thank you!!
