Nepal dog chews are preservative free, all natural dog treats made from the dried and compressed soft tissue of the Himalayan Yak and/or cow. They are considered to be a natural and healthy alternative to many of the processed dog treats that are available on the market today. It is important to note that it's best to supervise your dog while they are chewing to ensure that they don't accidentally swallow large chunks, which can cause choking or intestinal blockages.
