Chihuahuas are small dogs that can be lively and loud. The AKC notes they are also known for loyalty, alertness, and spirited nature. Chihuahuas have a "terrier temperament," meaning they are smart but may confuse puppy play with adult behavior. Even if they fit in a purse, they can be noisy. Consistent guidance is needed for the best results with these tiny dogs.
