So sorry you are sick, and I hate to add to your list of emails, but you asked once for a link to the claim that one of these blue dogs sucked blood, and here it is: "What tipped Canion to the possibility that this was no ugly coyote, but perhaps the vampirelike beast, is that the chickens weren’t eaten or carried off — all the blood was drained from them, she said."
Of course, she could be lying, but here it is, nonetheless. Also, this link http://www.absoluteastronomy.com/topics/Chupacabra and this link http://blogcritics.org/archives/2005/08/25/234533.php says the the DNA tests showed a coyote with mange.
Feel better!! I'm sick too :(
