Yakers found their origin in the hills of the Himalayas - originally made for human consumption they are still eaten widely by the Himalayan people and their dogs. They are made with a mix of skimmed Yak and Cow milk and a small amount of lime juice and salt. These chews are 100% natural, vegetarian and preservative and gluten free. Yakers treats are rich in both protein and calcium and help to fight plaque and tartar. Their hard texture means they can be a long lasting treat for your dogs.
