In August 2004, a strange canine was shot and killed by a local rancher. The animal weighed twenty pounds, severe overbite and unusual blue, hairless skin. Experts at San Antonio Zoo speculated due to the skull that it was a Mexican Hairless Dog. It was later determined to be a coyote with demodectic or sarcoptic mange and not originally hairless. However, DNA gathered was inconclusive due to environmental degradation, but it was proven it was from the canine family. Two similar carcasses were found in Texas and found to be coyotes with severe cases of mange.
