I did some light searching, and it would seem that your examples don’t support your viewpoint. I didn’t look into all of them, but there is only 1 truly wild horse species, which was actually extinct in the wild at one point. The rest are feral horses. Canis familiaris is the descendent of an extinct species. Many (most?) wolves and other wild dog species that do not live well among humans are either currently or were until recently endangered.
