Maybe Dog Picture? #1

I couldn't decide if today's picture is a dog picture or not so I made up a new type of picture called Maybe Dog. It is because the picture is not of a dog, like one that is alive, but it still shows a dog in the picture! You can see how easily it is to get confused! Anyway, this picture is of an ancient statue of a dog but the fascinating thing about it is that this dog has three heads! Did such a dog exist in olden times? I asked my history professor and not even he could break through this enigma! If you owned such a dog, would you give him one name or three? Today's update is very puzzling indeed! I give this picture a 9/10 for making me scratch my head in wonderment.
