Behavior
Shih Tzu have all the traits you could wish for: sociable, friendly, lovable, loyal, cheerful, and intelligent. They are well-suited to be companion dogs and because of their size, make great lap dogs. Training this breed, though, does require patience. They are affectionate with their families, but they can be good watch dogs because they are suspicious around strangers. They tend to want to be the boss, so it's important to be kind but firm with them to let them know who's the master. Otherwise, they'll tend to run the roost, which won't necessarily make them happy or pleasant to be around.
Coat
Shih Tzus' long coat is somewhat high maintenance and requires everyday brushing to prevent tangles. These dogs should be taken to a professional groomer every couple of months. They are usually easier to maintain when their coats are clipped short, but you can't argue that those who have the long, dreamy coats are dramatic and eye catching. Show dogs definitely need daily grooming to keep them looking perfect, but if you're looking for a Shih Tzu just for the fun, don't forget the occasional bath.
Lifestyle
Since they are small, this breed can adapt to apartment living or a big house. Shih Tzus are indoor dogs who get along with other pets very well and love to cuddle in your lap, making them great family companions. You would never want to limit these small dogs to just the outdoors.
