In approximately 1800, during the last hunt at the Vore Site, a wolf-dog was killed and left in the sinkhole. The dog probably belonged to the Cheyenne as there is considerable evidence that this tribe was the last to use the Vore Site. The skull was found during the excavation in 1970 in the first cultural level, the level corresponding to the last hunt at the Site.
Until the late 1700s the only beasts of burden used by the Plains Indian tribes were dogs. Dogs, the first domesticated animals in North America, were used for hunting, hauling, transporting, guarding campsites and as a food source. Breeding dogs with wolves was common. Five canid skulls have been found at the Vore Site. These skulls provide evidence that the Native Americans broke off or filed down the canine teeth…presumably to prevent the dogs from injuring their owners or other dogs and to prevent them from chewing through their tethers.
