This is not a Chupacabra . It really resembles a Peruvian hairless Dog. They are large hairless they also have very long legs which would make it look Kangarooish.And it looks as if it may be mixed with Coyote. That would exsplain the large ears.
The poor thing looks like it has been starved. That would exsplain it's bad skin. And the looks of the spine raised up off the back. Please look up pictures of this Peruvian Hairless dog. You will see that it has canine teeth. Which cannot be used for sucking Blood. I just wish people would contact the right people to cheak out these things before they try to make The poor animal suffer after it's death in a shop someplace just to make money.
