I've written before, as have others, that these so-called "chupacabras" seen in the Southwest are not the crypto-creature from Fortean or paranormal realms. These hairless 'blue dogs' are simply mundane animals. Either mange or some other disease, or, as Lon Strickland of Phantoms and Monsters writes:
a hybrid species of Mexican wolf and another canine species. Ken Gerhard and Jon Downes have done extensive study and have written about this cryptid canine. I just wish people would stop killing the 'blue dog' just because it's been given the 'chupacabras' moniker. Below are previous posts on this cryptid...LonI don't how the meme got started that these unusual looking canines were chupacabras, or why people are killing them.
Here's a quote from crypto researcher Jon Downes from Lon's posting of the article Searching for Blue Dog Facts:
It is a very weird and very interesting member of the dog family; it has nothing to do with this weird folklore," said Jonathan Downes, a former zoological journalist and self-taught amateur "cryptozoologist" from West Devon, England.
