How many wild canines can you name? There are wolves, foxes, and coyotes, and lots of other wild dogs in Africa. Dingos are descendants of domesticated dogs that became wild again. Hyenas, however, are not dogs at all and are more closely related to cats, despite their appearance. Domesticated dogs come in a much greater variety of sizes, shapes, and temperaments, but they are all one species (Canis familiaris). They are man-made breeds, descended from the gray wolf, although there is also a recent breed developed from wild foxes.
MinuteEarth gives us an overview of the different kinds of dogs, starting with some examples of extinct canids, then moving to wild dogs of the world and ending with domestic dog breeds and mutts. You might get the idea that this is a ten minute ad for a poster they produced, and you'd be right. But the selling part is not intrusive and the subject matter is interesting enough on its own.
