They are Not Perfect
It may seem like from the description that Shih Tzus are perfect. Well, they can be somewhat arrogant as they live with the king or queen of the home. It is this pride that makes them less than perfect, but no less desirable. The fact that they are not perfect only makes them better for you and your family when looking for the right dog.
If you have considered owning a dog, then a Shih Tzu is a good place to start. They are warm, loving, and attentive dogs because that is what they are bred to do. They also bring out the best in their owners which is yet another reason it may be the best breed of all.
