The Maned Wolf is a dog, but not a wolf. YouTube member EndangeredWolf explained more about its classification:
They are a member of the dog (Canid) family as are wolves. But they are not in the same genus as wolves (Canis). They are the sole remaining remnants of the prehistoric carnivore from South America whose scientific name is Chrysocyon brachyurus and are the only species in their genus. They are omnivores whereas wolves are carnivores. They are solitary animals and wolves are very social. They 'roar-bark' rather than howling. The list goes on, but they are unique and amazing.
