These Yakity Yak dog chews are hand crafted from a blend of 100% Yaks/cows milk with a little lime and salt and then smoked to form a hard, tasty, cheesy chew. The Himalayan people (and their dogs!) have been enjoying these tasty snack chews for generations. Every dog has a natural need to chew. This often starts when they are puppies, and progresses to chewing our table legs and shoes! Chewing gives natural dental care and occupies the dog. From the heart of the Himalayan Mountains, these Yak chews are great for giving your dog something tasty and robust to chew. When the chew gets too small for your dog, just pop it in the microwave and puff it up for a tasty snack! The reason I LOVE these is because they contain no artificial colours, preservatives or flavours, just 100% tasty goodness!
