Yellow Yak Yum starts with our favorite ingredient - cheese. Using a traditional Himalayan recipe, our chews are lactose, gluten, and grain free, 100% natural, and easily digestible! Yellow Yak Yum is a medium density chew that is great for all chewers! It lasts about as long as a bully stick of the same size/ Yum comes in four flavors - original cheese and with bacon, peanut butter or chicken. Yellow Yak Chews are available in Hard, Medium, and Soft densities. We make a variety of sizes and flavors guaranteed to keep your dog satisfied!
