Golden jackal, jungle cat, wild dog, dhole, leopard and tiger are the main predators. Carnivores include the tiger, wild cat, jackal, leopard, and dhole (Indian wild dog). According to zoologist Reginald Pocock, a dhole interbred with a golden jackal. Leopards, dhole packs and large mugger crocodiles occasionally attack unguarded calves or unhealthy animals. In Southeastern Asia, golden jackals have been known to hunt alongside dhole packs. The Ussuri dhole is the largest subspecies. In this respect, the dingo resembles two similar mesopredators, the dhole and the coyote. Methods used for dhole hunting included poisoning, snaring, shooting and clubbing at den sites. The dhole (Asian wild dog) is a major predator. The etymology of "dhole" is unclear. The dhole still occurs in Tibet and possibly also in North Korea. Big Bears features a brown bear exhibit and the new dhole exhibit. Detweiler says the dog is a Wanshang Dhole, a species thought to be extinct. He promptly transforms into the murderous dhole and attacks the catcher. The dhole only rarely takes domestic livestock.
