Go to texasescapes.com. Click on 'columns.' Click on 'Charley Eckhardt's Texas.' Scroll down to 8-15-07--'Mysterious Cattle Deaths' Not So Mysterious.' That column explains the so-called 'sucked dry of blood' bushwa. An old friend, the late Mike Bradshaw, at the time a Texas game warden, took part in the investigation of one of those cases. He explained, in detail, just exactly what's happening. There are no aliens, satanic cults, 'chupacabras,' or secret govt. experiments involved. It's all nature.
I have seen photos of perhaps a dozen of the so-called 'chupacabras.' Every one has been either a coyote or a domestic dog afflicted with what we used to call 'blue mange.' It was fairly common back in the great drought of the '50s. You saw one, you shot it, dragged it up to a brush pile, & set the brush pile afire. That prevented the spread of the stuff. I understand if you catch the stuff in its early stages & treat the affected area by smearing it with used motor oil you can cure it, but once it's gone as far as what you see in the pictures, just put the critter out of its misery & burn the carcass.
