Is Chupacabra real?Or is it some dog infected with an unknown disease?

I was on msn today and I was bored, so as I flipped through videos, I came to this video “Hunting the Elusive, Mythical Chupacabra”: http://www.bing.com/videos/watch/video/chupacabra-re-examined/p1d1j69?q=Chupacabra&rel=msn&from=en-us_msnhp&form=msnrll&gt1=42010.
Do you think the Chupacabra is real?
