I was watching a documentary on the "El Chupacabra" and I thought of my friend Chip the freakhound ! Freakhounds truly look like these blood sucking critters. Take a look -->http://www.ginalanier.com/Chupacabara.php (scroll down the page a bit) then combine that with the ones of legend (the one's with the spikes and all) And there you have it. One freakishly mutated coyote thus known as "The freakhound" Case solved.
