The purpose of the article was to explain the myth that the so called goat sucker is not a Chupacabra but a dog that has become infected with mange. The article gives you confirming information that the mite that is responsible for the extreme hair loss seen in "chupacabras syndrome" is Sarcoptes scabiei, which also causes the itchy rash known as scabies in people. Human scabies is an annoyance, but not usually a serious health or appearance problem, partly because our bodies are already virtually hairless and partly because the population of mites on a given person usually is relatively small---only 20 or 30 mites. The article also explains why they are also known as goat suckers. When they are in a weakened state they must hunt in order to try and build up their strength. They mostly hunt the livestock that people have as pets because it is contained and easier for them to find rather than go looking for other means of food. In conclusion scientists deems the myth of the Chupacabra as a coyote that has come in contact with mange.
Here is an example of what the animal looks like.
