Members of the dog family can be broadly divided into two groups. One goup are the vulpines, including such familiar animals as the red fox and its Arctic relative. The other are the true canines, a rather more diverse group found wild on every continent bar Antarctica. While species in the first group are all basically fox-like, those in the latter are not necessarily "wolf-like". Indeed, the second group includes the zorros, or South American foxes, which descend from a more wolf-like animal that nipped south when the two American continents collided.
Still, the second group does include animals that are more obviously wolf-like, such as the wolves themselves, along with coyotes, jackals, dingos, and so on. But there are also a number of species that are more distinctive, and while (in most cases) clearly dogs of some kind, aren't that much like our normal ideas of either wolves or foxes.
