Welcome to Gaia! ::

Obviously something is killing chickens, but looking at those dogs, they look more like daytime scavengers, not prey driven animals. They do look like the Mexican stray dogs. Or the Xoloitzcuintli (Mexican Hairless.) Probably cross-bread with coyote, but I don't think they could suck the blood out of animals. That doesn't make sense for the anatomy of the dog's teeth and jaws. Maybe it would kill the chickens, but I don't understand why it wouldn't eat the meat.

Here's a photo of what the dogs look like:

They also come in a variety of sizes and colorations. not exactly the prettiest creatures in the world... but I kinda want one. ^_^

That... plus this: http://www.desertusa.com/mag02/nov/coyote2.jpg
You can definitely see the resemblance in the one they were calling the Hoyote. The front legs, ears and fur patches look like Coyote, the rest is probably Mexican Hairless.

And there's next to no possibility of it also being cross-bread with a kangaroo.
a) they're not indigenous to America
b) they're not even close to being the same species. A canine and a marsupial could not mate.

Ditto for the wolverine theory; and the rat theory is rediculous.

As for the freakish dogs that they saw, well, dogs have a habit of breading weird mutant genes. It wouldn't take long for a dog with a long tail, short front legs and long back legs to appear. Although, the video footage of the animal rummaging around doesn't look like it has especially long back legs; and certainly not the type that would easily or naturally help it stand upright.

I think something is going on here, but they could get more viable evidence. They could tranquilize one of these animals, instead of killing it, and examine it. They could also set up surveillance cameras around the chicken coops to see what's really going on.

Did anyone else catch that new program about it? They found a body that looks like the one in that video, turns out it was a cross between a coyote and either a gray or Mexican wolf. They don't know why it was hairless and think it's a genetic disorder or caused by a disease. They also tested the organs but said that they don't think it could have just lived on blood.

I think it was on Discovery, I can't remember though.

I'm curious though... People are saying that's what they saw killing their animals but if that's what it is, then why isn't it eating the meat, and if it is living off blood why aren't it's organs showing that it's possible?

Anyway, they still really remind me of Tasmanian Tiger's. The Tasmanian Tiger had similar foot prints with the larger pad and four toes. It could also stand up like people have said the Chuppacabra could do. I could see why people would relate that back to a Kangaroo.

-The thylacine was able to open its jaws to an unusual extent: up to 120 degrees.

-Thylacine footprints could be distinguished from other native or introduced animals; unlike foxes, cats, dogs, wombats or Tasmanian devils, thylacines had a very large rear pad and four obvious front pads, arranged in almost a straight line. The hindfeet were similar to the forefeet but had four digits rather than five. Their claws were non-retractable.

-The thylacine was noted as having a stiff and somewhat awkward gait, making it unable to run at high speed. It could also perform a bipedal hop, in a fashion similar to a kangaroo—demonstrated at various times by captive specimens. Guiler speculates that this was used as an accelerated form of motion when the animal became alarmed. The animal was also able to balance on its hind legs and stand upright for brief periods.

-The thylacine was a nocturnal and crepuscular hunter, spending the daylight hours in small caves or hollow tree trunks in a nest of twigs, bark or fern fronds. It tended to retreat to the hills and forest for shelter during the day and hunted in the open heath at night. Early observers noted that the animal was typically shy and secretive, with awareness of the presence of humans and generally avoiding contact, though it occasionally showed inquisitive traits.

Still, Tasmanian Tigers were carnivores and wouldn't feed on blood alone.
