Chihuahuas are named for the Mexican state of Chihuahua, and the AKC registered its first one in 1904. Most pet Chihuahuas weigh between 3 and 9 pounds, with an apple-shaped head, large upright ears and a smooth or long coat in almost any color. Shedding is low to moderate, so regular brushing is usually enough.
The personality runs bold and alert. Many Chihuahuas bond closely with one or two people, bark at unfamiliar sounds and may snap if handled roughly, so gentle socialization matters. They often live 12 to 16 years, which is a long commitment. In State College, their size makes them easy to carry through a crowded downtown sidewalk or settle into a small rental.
