In the language of the Native American, Ioway people, the expression Shunka Warak'in means "carries off dogs". This name has been applied to a cryptid that is said to inhabit the great plains of North America. A purported specimen of this cryptid was shot in Montana, around the turn on of the last century, by a member of the Hutchins family. This specimen was later mounted and displayed at a general store and museum in Henry Lake Idaho where the owner called it "Ringdocus."
There is much speculation about the identity of the Shunka Warak'in, the mounted beast, and whether the mount is in fact a Shunka Warak'in. To some the mounted beast is simply a poorly mounted wolf. Various other possible identities that have been proposed for the "Ringdocus" in particular, and for the Shunka Warak'in in general, include various canid species such as the Dire Wolf, various hyaenid species, a creodont such as borophagus, some type of gracile hyeanodon, or even a long-nosed peccary.
The current location of the mounted specimen is unknown and the whole question of its identity and that of the Shunka Warak'in remains a mystery.
