Why were chihuahua bred?
The Chihuahua as we know it today is a much more diminutive dog than its predecessor. It is theorized that the Chinese Crested, brought from Asia to Alaska across the Bering Strait, was responsible for the reduction in size. Modern Chihuahuas are also found in a myriad of colors. The Chihuahua is an older breed by American Kennel Club standards, first registered in 1904.
