The Havanese is the best breed of dog to be a friend to humans, with a high level of intelligence, understands at a glance, and is very attached to its friend. It is the best psychological treatment for humans. Playful, loyal, not annoying, clean, and easy to train. Within five days, it knows its designated bathroom spot, and after that, you won't notice it; it will be the one to alert you when it wants to go to the bathroom. Its size after maturity is small, slightly larger than a cat. So cute.
