7. Over-exercising
Regular exercise is definitely beneficial for the overall health of your Shih Tzu, but you need to be careful enough not to exceed the limits. Shih Tzus have lots of energy, but they are small dogs and don't need a huge amount of exercise. A couple of short walks a day, plus regular indoor or outdoor playtime is more than sufficient, so don't expect your Shih Tzu to be able to accompany you on lengthy or difficult hikes or adventure sports – that's a bit too much to expect for such little legs.
