No, they’re the same species: Canis lupus. Dogs are a subspecies, Canis lupus familiaris. But they’re still related closely enough to produce fertile offspring, so they’re considered the same species.
Yeah, dogs were reclassified to be the same species as grey wolves in 1993 by the Smithsonian Institution.
The fertile offspring method of classification isn’t why they were reclassified though, and while it’s a good guideline isn’t the beginning and end of the discussion.
