I don't know what Chupacabra was described to these people. They obviously don't know too much about the myth if they're comparing it to a fuckin canine. All the stories I've ever heard about when describing a chupacabra have resembled a creature looking something like this drawing.
See the name means "goat sucker". They called it that because people kept finding dead goats with either a single large hole or a few tiny ones in thier necks and their bodies we're completely drained of their blood. Though they did describe it as something that looked half kangaroo/half reptilian...kinda like a dragon of some sort. Though that creature looks a lil like a roo....theres no way that little fucker sucked goats dry from the neck. Plus the teeth are all wrong. That thing has canine teeth. It wouldn't puncture and suck them dry...it would tear off pieces of them.
Asta!!
