The Chihuahua is the smallest breed of dog in the world. It is also the only “natural” toy breed of dog.
Breed standards for Chihuahuas do not specify a height, only a weight and a description of their overall proportions. As a result, height varies more than within many other breeds. Generally, their height ranges between 6 to 10 inches (15cm to 25 cm). Chihuahuas are known for their devotion, ferocity, and personality. Their curious nature and small size make them easily adaptable to a variety of environments.
