Chihuahuas are named for the Mexican state of Chihuahua and are one of the smallest dog breeds in the world, usually between 3 and 9 pounds in pet homes. They have an apple-shaped head, large upright ears and either a smooth or long coat in nearly any color. Shedding is low to moderate, so coat care stays light.
Many Chihuahuas are devoted to one or two people and carry a big-dog attitude, which can mean barking and suspicion of strangers. They're fragile, too: dental disease, slipping kneecaps and chilling quickly are common concerns. Not every Chihuahua fits that pattern, and gentle socialization and patient training help a nervous dog settle. In Springfield, that mix of small size and strong opinions shapes everything from walks to winter gear.
