Some fine person has provided us the appropriate weasel words at Wiki:

"Currently, the domestic dog is listed as a subspecies of Canis lupus, C. l. familiaris, and the Dingo (also considered a domestic dog) as C. l. dingo, provisionally a separate subspecies from C. l. familiaris; the Red Wolf, Eastern Canadian Wolf, and Indian Wolf are recognized as subspecies.[1]

Many sources list the domestic dog as Canis familiaris, but others, including the Smithsonian Institution and the American Society of Mammalogists, more precisely list it as a subspecies of C. l. familiaris; the Red Wolf, Eastern Canadian Wolf, and Indian Wolf may or may not be separate species; the Dingo has been in the past variously classified as Canis dingo, Canis familiaris dingo and Canis lupus familiaris dingo."

They are regularly mated together ~ all of them ~ much to the distress of their owners who imagine them to be different species.

I didn't reply to your contention that wolves and dogs are the same species. They share such a recent evolutionary origin - and their separation is driven by human mating so much that it makes for a less precise delineation.

I did reply to your contention that wolves and coyotes are the same species. They are not, any more than tigers and lions are the same species - despite the fact that they can produce fertile offspring.

Come to Nevada. I can show you 90 pound animals that look exactly like their 35 pound “coyote” relatives. Somebody let a Great Dane into the woodpile.
