Chihuahuas are named for the Mexican state of Chihuahua, and the AKC registered its first one in 1904. They're a toy breed with an apple-shaped head, large upright ears and either a smooth or long coat in nearly any color. Most pet Chihuahuas weigh 3 to 9 pounds, and many live 12 to 16 years.
Many Chihuahuas are devoted to one or two people and act far bigger than they are. They may bark at visitors, be wary of strangers, or snap if handled roughly, so gentle socialization and reward-based training matter. Care in Elmira centers on warmth, dental upkeep and a harness rather than a collar. Dogs vary, so a Chihuahua's own personality counts for more than the breed label.
