Himalayan Dog Chew was born from an ancient recipe for a hard cheese snack chewed by the people if the Himalayas. In the mountains surronding Mt. Everest at more thatn 15,000ft, it is made using traditional methods with yak and cow milk, and all natural products with no preservatives or binding agents. They're also gluten free! Depending of the size and eating habits of your dog, this can be a very long-lasting chew. Dogs must work the end of the treat for hours, softening it with their mouths before small parts of it can be slowly chewed off. When you give this treat to your dog, you know that you are providing them with high-quality eating entertainment.
