Himalayan yak cheese is a nutritious, easily digestible and safe chew for your dog to enjoy! Our product is made from free range organic yak's milk. The soft cheese is pressed in a jute bag until the water is pushed out. It is then cut into strips and smoked for up to 28 days to cure and harden. Traditionally, in the Himalayas, the hardened cheese is moistened before eating. However, the hardened cheese is so dense that it makes for an excellent long lasting natural chew for dogs! Not only does it satisfy your dogs' natural instinct to chew, but it also promotes oral health by fighting plaque and tartar buildup. This in turn makes your pup's teeth cleaner and breath fresher! Because no preservatives are used in the process of making yak cheese, your dog won't be exposed to adverse chemicals. This also minimizes the choking hazards associated with dried bones, rawhide style chews, and plastic/nylon chews. Oh ya, we almost forgot to mention, they don't stink up the house like other natural chews do (phew)!
