    Canadian Inuit Dog

    The Canadian Inuit dog (Canis familiaris borealis) is one of five dog breeds recognized by the Canadian Kennel Club as uniquely Canadian (see also Dogs in Canada). While the Canadian Kennel Club refers to this breed as the “Canadian Eskimo dog,” the Government of Nunavut calls it the Canadian Inuit dog and made it the territory’s official animal. In the Eastern Baffin dialect of Inuktitut the dog is called qimmiq (spelled Kimmik in other dialects). For hundreds of years, these dogs were used by the Inuit and their ancestors to pull sleds as a means of transportation. From the 1950s to the 1970s, the Royal Canadian Mounted Police and other government officials killed thousands of sled dogs, rendering the breed extinct. Since then a revitalization program has helped re-establish the Canadian Inuit dog. As of 2018, there are approximately 300 Canadian Inuit dogs registered with the Canadian Kennel Club.
