However, a report has surfaced, including pictures, of three animals found over four days outside the ranch of Phylis Canion in Cuero, TX. Cuero is 80 miles southeast of San Antonio. The animals, according to Canion, are approximately 40 pounds, and she has termed them Chupacabras based on a resemblance to the reputed appearance of the beast.
According to Wikipedia, here's how the Chupacabra has been described:
The most common description of Chupacabra is a reptile-like being, appearing to have leathery or scaly greenish-gray skin and sharp spines or quills running down its back. This form stands approximately 3 to 4 feet (1 to 1.2 m) high, and stands and hops in a similar fashion to a kangaroo. In at least one sighting, the creature was reported to hop 20 feet (6 m). This variety is said to have a dog or panther-like nose and face, a forked tongue, and large fangs. It is said to hiss and screech when alarmed, as well as leave behind a sulfuric stench. When it screeches, some reports assert that the chupacabra's eyes glow an unusual red which gives the witnesses nausea.
Another description of Chupacabra, although not as common, describes a strange breed of wild dog. This form is mostly hairless and has a pronounced spinal ridge, unusually pronounced eye sockets, fangs, and claws. It is claimed that this breed might be an example of a dog-like reptile. Unlike conventional predators, the chupacabra is said to drain all of the animal's blood (and sometimes organs) through a single hole or two holes.
Looking at the pictures, it could be some sort of mutant dog or something. Interestingly, there was a second report of a Chupacabra in OK. What's also notable is that the pictures of the second animal seem pretty similar to the ones from TX. And the timing is uncannily right around the same time (now).
In the OK case, however, the person who found the Chupacabra in OK wanted to remain anonymous.
What made Canion, on the other hand, believe this was a Chupacabra rather than just a mutant dog is that the chickens on her ranch that she believes were killed by the beast weren't eaten or carried off. Rather, all the blood was drained from them. The Chupacabra's Spanish name (literally, goat sucker) comes from its reputation of of attacking and drinking the blood of livestock, especially goats.
Mutant dog or Chupacabra? You decide.
