Domche from Laya village in Gasa Dzongkhag (district), shares an account of a Yak called Zhaw Laga. According to him it is believed that the yaks of Laya village originated from Yak Zhaw Laga, a treasured yak and descendant from Yak Lhadar Gaw of Soe Gewog (county) in Paro district. Yak Zhaw Laga was considered important because the yak had extracted water from the ground in a previously arid place by digging with his horns. Besides this event in Tongra, there are other different places where the yak left an extraordinary imprint. Later district administrators took the yak to Gasa Dzong in order to kill it, but the special yak disappeared from the Dzong and transformed himself into a mountain just opposite to Gasa Dzong, which can still be seen today. The yak's blessing traveled to Dagana and today that district is believed to have some of the best quality yak in the country.
