The Chihuahua may be the smallest breed, but that doesn't stop them from being full of personality and spunk! They can be strong-willed without proper training and need frequent and consistent obedience training. Despite their specific needs, Chihuahuas make wonderful lapdogs and are extremely loyal companions. They are very adaptable and make great pets, even for those living in small apartments. The Chihuahua is a medium energy breed with low exercise requirements and most would rather be carried in your arms wherever you go!
