We all know that the domestic dog comes from the wolf,however there seems to have been experimentation with other canids. The Hare Indian dog and Tahtlan bear dogs may well have been domesticated coyotes and the Selk'nam people tamed a close relative of the warrah. Plus the Island fox may'v been kept by California Native Americans,the fennec is commonly kept as a pet, Russian domesticated red fox and Sulimov jackal-dogs. I know why the wolf was the most successful and don't want that eliminated. Just the possibility of other canids that were thru selective breeding were domesticated,widespread and used.
