From the Manufacturer;
Livstrong Pets Himalayan Yak Cheese is a 100% natural, long-lasting chew made from an ancient Himalayan recipe in Nepal.
Using only 3 ingredients – Yak Milk, Lime & Sea Salt, it is a perfect chew for all-sized dogs. As the cheese is hardened it becomes lactose-free so easy to digest and contains no preservatives. Our Himalayan Cheese Yak Chews are flown in direct from Nepal ensuring freshness.
When there is a small piece of the chew left over, simply microwave it for 30 seconds until it puffs up like popcorn, let it cool and feed it back to your furry friend!
