The Chupacabra, the Dog, and the Dog One

The Chupacabra is said to have killed and drained livestock on a farm in Puerto Rico. Some people claim they've seen the creature, but others say it's just an urban legend. What else could have done that to those livestock? Mm-hmm. But I don't know anything that does that personally. Aliens. No, if it would be aliens or vampiric animals you probably would think of them as well.
