Chihuahuas may be small, but these tiny packages are chock-full of personality. Classified as a toy breed by the AKC, they are generally bred to be less than 6 pounds (3 kilograms), but every ounce counts. And despite his diminutive size, a Chihuahua will have no problem standing up to (or even acting aggressively toward) much bigger dogs. According to the AKC, Chihuahuas are partial to only one dog breed -- their own.

Bred to be a companion to humans, the Chihuahua takes its job seriously. According to breeders, they are protective, jealous and will guard you using their yappy bark when they see fit. Chihuahuas have been known to exclude members of their own human family and remain faithful to only one person. But these lively, funny little dogs flourish under human contact, and are dedicated to their beloved owners. They want to be with you 24/7 and require constant companionship to be truly happy.
