Above) Named for his sweet disposition, three-pound Honey is nevertheless capable of becoming possessed by the devil. He's not getting mad at the photographer, but at his fellow chihuahua, Monty. The kid in the background is TJ.
The photograph is by Jason Tromm, and if you search his Flickr photostream with the word "chihuahua" you'll find many pictures of chis Honey, Monty and Louie.
Below) The demon-chihuahua below was photographed by an unexplained mysteries buff, the pseudonymous "Raptor Witness." This dog looks just like Jason Tromm's Honey but isn't. So this must be a subspecies of chihuahua that comes from Hell, which is why the type look so similar.
