35. Chihuahua

The Chihuahua is a little dog that can occasionally be lively and noisy. The AKC claims that they are also renowned for their loyalty, politeness, and big-dog attitude. Chihuahuas have a “terrier temperament,” which means that while they are intelligent, they are prone to equating certain pastimes they enjoyed as puppies with appropriate adult behavior. This means that even though they may be small enough to fit in a pocketbook, they make quite a bit of noise. Therefore, in order to get the best outcomes with these tiny ones, it’s essential to be strict with them.
