What animal has long claws and a long skinny tail?

THE CHUPCABRA!!! I saw it on youtube. It's an animal that looks like a dog, it's big like a coyote, has really long back legs, a long snout, long claws, and a REALLY looong skinny tail. It also has 4 really long sharp canines. Just type in CHUPACABRA MYSTERY FINALLY REVEALED on youtube and watch. It's pretty darn creepy. Wouldn't want to run into one of those things ever.
