Prey animals in India include chital, sambar, muntjac, mouse deer, swamp deer, wild boar, gaur, water buffalo, banteng, cattle, nilgai, goats, Indian hares, Himalayan field rats and langurs.[4][11][42] There is one record of a pack bringing down an Indian elephant calf in Assam, despite desperate defense of the mother resulting in numerous losses to the pack.[12] In Kashmir, they may hunt markhor,[42] and thamin in Burma.[11] Javan rusas are hunted in Java.[28] In the Tien Shan and Tarbagatai Mountains, dholes prey on Siberian ibexes, arkhar, roe deer, maral and wild boar. In the Altai and Sayan Mountains, they prey on musk deer and reindeer. In eastern Siberia, they prey on roe deer, Manchurian wapiti, wild boar, musk deer, and reindeer, while in Primorye they feed on sika deer and goral too. In Mongolia, they prey on argali and rarely Siberian ibex.[43] Like African wild dogs, but unlike wolves, dholes are not known to attack people.[44][45] Dholes eat fruit and vegetable matter more readily than other canids. In captivity, they eat various kinds of grasses, herbs and leaves, seemingly for pleasure rather than just when ill.[46] In summertime in the Tien Shan Mountains, dholes eat large quantities of mountain rhubarb.[43] Bael fruits are also eaten.[47] Although opportunistic, dholes have a seeming aversion to hunting cattle and their calves.[48] Livestock predation by dholes has been a problem in Bhutan since the late 1990s, as domestic animals are often left outside to graze in the forest, sometimes for weeks at a time. Livestock stall-fed at night and grazed near homes are never attacked. Oxen are killed more often than cows are, probably because they are given less protection.
