After researching and asking about the pictures on Yahoo! Answers, the answer finally came out from a member known as Sirenheart (click here to go to Yahoo! Answers). The chupacabra in the picture is really a Xoloitzcuintle (pronounced show-low-eats-queen-tlee). It's a rare breed of Mexican hairless dog (see picture below) that has been around in the Americas for thousands of years and were even kept as pets and for food by the ancient Aztecs.
