A lot of mythology, folklore and exaggeration has sprung up around the so-called Texas Chupacabras (or hairless canines, to give them their correct description). Yes, they look weird; yes, there may be a few odd genetic anomalies going on with them too. But they have nothing to do with the Chupacabras of Puerto Rico in the slightest.
It's a name, a media-tool, a word ingrained in popular-culture, and it's something I discuss in this new article at the website of the Dallas-Fort Worth, Texas-based DFW.com magazine. And, if you live locally, you can read the same article in the printed edition of the magazine too.
