Chihuahuas take their name from the Mexican state of Chihuahua, and the AKC registered its first one in 1904. Most adoptable Chihuahuas weigh between 3 and 9 pounds, a bit more than the show standard allows, and they come in a smooth or long coat in nearly any color. Shedding is low to moderate, so grooming mostly means regular brushing.
Personality runs from bold to timid. Many Chihuahuas bond tightly with one or two people, bark at unfamiliar sounds and may snap if handled roughly, so calm, gentle handling matters. They often live 12 to 16 years, which is a long commitment. Their small size and modest exercise needs are an advantage in a town of older houses and apartments, though dental care and cold protection need steady attention.
