Our dog chew is sourced from Yak and/or Cow farmers from the foothills of the Himalayas in Nepal. The chew is quality tested by independent laboratories in Nepal and in the US to maintain and validate the overall quality of Durkha Dog Chew. It’s natural, preservative-free, gluten free, grain free, odorless and protein rich with low fat content. The chews are long lasting and easily digestible, so they are a great and safe alternative to rawhide.
