Legend has it than in ancient times the Tibetan Mastiffs were kept as guardians of the monasteries in the Himalayas. Due to Monks being vegetarians, these Mastiffs were fed Sherpa Chews aka "Churpi", a high-protein chew for nutrition. Asa result, they were thought to be strong enough to break metal shackles if they anticipated any therat to them or their master.
Using this ancient recipe passed down over generations, the hardened cheese - Sherpa Chews - are hand-made at over 15,000 ft in the foothills of Himalayas. To preserve the nutrition of milk & to substitute the low availability of vegetables, Sherpa chews are still consumed as food in these regions and thoroughly enjoyed by both humans and the pets alike.
