Description: The Chihuahua is the smallest breed of dog in the world and was named after the state of Chihuahua in Mexico. He is a graceful, alert, swift-moving little dog with a saucy expression. Two distinct breed types, one with a long coat of soft texture, the other with a short coat. Identical otherwise, both can be whelped in the same litter. Adored for his small size, the Chihuahua is a bright eyed, dainty dog who is perfect for apartment living. Most breeders recommend adopting a Chihuahua puppy between the ages of 4 - 12 months as he will be more mature and agile and not so apt for injury.
