Do wild dogs still exist?

The classification as wolf, fox or wild dog remains difficult for some canids, such as the Abyssinian Wolf Canis simensis , 500 of which live in present-day Ethiopia.
But even if we exclude wolves, some wild dogs continue to exist, including the New Guinea Singing Dog, Indian and African Pariah Dogs, the Basenji of Congo (many of which have been domesticated and recognised by the FCI), Carolina dogs and Australian dingoes. All wild dogs have a similar morphology.

Could dogs become wolves again?

Starting from the principle that evolution never goes backwards, researchers at the University of Rome studied colonies of wild dogs living in the Abruzzo region of central Italy. They noticed that dogs in the forests lived like wolves, in packs with clearly defined territories, while stray dogs in the villages generally only looked out for themselves.

However, wild dogs do not look like wolves. They are smaller and of an amber-brown colour, which signifies they have lost some alleles forever, no doubt as a result of a period of domestication in their history.

From fossils and mitochondrial DNA tests, scientists know that dingoes Canis lupus dingo are descended from a small group of more or less domesticated dogs that were introduced to Australia by Asian sailors some 3,500-5,000 years ago and returned to the wild. Classified among domesticated and wild dogs for 50 years, dingoes are now classified as a subspecies of the Grey Wolf, although research is still ongoing to provide conclusive proof of this relationship
