I'm not sure if the mangy coyote's are siphoning blood from the victims or not. If they are this would probably put them closer to the chupacabras category. They do not resemble or seem to resemble the typical chupacabras that has been seen. I guess the chupacabras has bat wings, sharp teeth and they are not dog or canine looking. In the cases of chickens being attacked and other animals I seem to believe I read that the blood is missing when the coyotes are found as well as the chupacabras. Maybe someone knows for sure.

If a small animal like a chicken is attacked by a fox or coyote or any other large carnivourous preditor then there is not gonna be much blood left, in fact, if anything has its head ripped off then you can bet that there isnt gonna be much blood left in it when its body is found ......... take a look on the supermarket shelves at chicken and you won't see any blood.

If your asking wether they drain blood from a victim like a vampire and return again and again to the same animal like we milk a cow then you have been reading some strange fantasy stuff my friend !

Interesting...

im a bit of a chupacapra exepert and most of the time they find sqare punctuere marks but no gouges or tears and not a drop of blood inside kinda sick actually
