Shih Tzus are usually calm and gentle, though they may be playful and feisty at times. The breed typically makes a good children’s pet.  They do not take severe punishment well. 

Generally outgoing and friendly, the Shih Tzu has an attitude that cries to be spoiled.  The breed’s strong sense of self makes it a poor choice in a household with babies or small children, as it is often jealous of babies and toddlers, and may snap if bothered by rambunctious children.  However, the Shih Tzu is a fine companion for older children, particularly those who enjoy combing its coat.

Shih Tzus are active and alert, qualities that make them good watchdogs.  However, poorly bred dogs may be excitable, noisy, and snappy.

Shih Tzus are intelligent and can be trained for obedience, competition, and good manners around the home.  They can be stubborn, so persistence and consistency are important during the training process.  Punishment makes this breed shut down, so training should be low-key and motivational.

Shih Tzus are generally easy to care for, but the area around their eyes should be cleaned gently each day.  Most Shih Tzus enjoy exercising outdoors and, when exercised regularly, have plenty of stamina.  Most enjoy long walks, although they are also quite happy to run around the house.  A dog whose coat is allowed to grow out needs daily brushing to avoid tangles; a short haircut eliminates this extra care.  Shih Tzus do not tolerate cold temperatures well, so longer hair during the colder seasons is more appropriate than a short coat.  Shih Tzus are considered to be brachycephalic (snub-nosed) dogs.  As such, they are very sensitive to high temperatures.  This is why airlines that ship dogs will not accept them for shipment when temperatures may exceed 75 degrees Fahrenheit (24°C).
