Our Yak Cheese Dog Chews are 100% natural, low fat, hard cheese chews that originates in the Himalayas. Our smoke-dried chews are made from Yak and Cow milk, to give a truly unique, tasty and low fat treat that your dog will love. With no added chemicals or preservatives, these natural treats are low in fat, rich in calcium and protein and also help with your dog's dental hygiene. As your dog chews the hard cheese, it gradually softens, helping to remove plaque and leaving a softer, chewy cheese treat for your dog to enjoy.
