Durkha is a yak milk based ancient recipe prevalent among the people living in the Himalayas who have been enjoying it for centuries. After boiling pure yak milk, it is cooled down and all the fat is removed. The fat free milk is now boiled and mixed with lime and salt, removing the lactose and leaving just the protein making it easily digestible for dogs. Next, all the moisture is extracted, a process that takes almost 2 weeks, resulting in the hardened Durkha being cut into different shapes and sizes. Lastly, it is smoked for four months to give it the flavor dogs love. When the chew gets too small, simply microwave the leftover piece for 45 seconds, let it cool down for 2 minutes, and give the yummy Durkha puff to your dog.
