Yaky Charms are made using techniques by the people of the Himalayas, derived from an ancient recipe to convert milk into a hard cheese (these don #39;t actually contain any corn, they are all cheese!). The same method is practiced at HIMALAYAN DOG CHEW #39;S farm in Washington State to create an authentic treat that is 100% natural without any preservatives nor additives. Now the same Himalayan treat in the form of charms are available to you and your dog. Lactose, grain, and gluten free! INGREDIENTS: Cheese (cultured, pasteurized skimmed milk), Salt, and Lime Juice.
