Chimhuauas

Half primate, and half canine, these beasts are all terror. They hunt in small bands of 5-10 individuals. More than ten, and the group's instincts turn inward, sometimes eliminating the entire band in a matter of minutes. Primarily bipedal, Chimuauas are capable of extreme speed on the ground or in the trees. They have fierce claws, razor-sharp fangs, and enough strength to carry more than twice their body weight. Chimuauas possess an instinct to kill greater than almost any living being in the universe.

If it weren't for the fact that they rarely exceed 10" tall at full extension, they would be a formidable assailant.
