Many Shih Tzu owners leave a bowl of dry dog food out all day. The puppy can eat when it feels hungry. This method provides the animal with ample nutrition to meet its growing needs.
Leaving a bowl of dog food out for the animal to tuck into at any time can result in problems associated with over-eating. Shih Tzus aren't the most active of dogs and they can suffer from obesity-related conditions.
A Shih Tzu puppy needs to be fed three times a day. It should eat 28 g (1 oz) of food for every 450 g (1 lb) that it weighs. For example, if the puppy weighs 2.26 kg (5 lb) it should eat 142 g (5 oz) of food at each meal.
A scheduled and measured diet is healthier for Shih Tzu puppies. Free-fed puppies do not develop disciplined eating habits. In addition, it is difficult to get the puppy into a housebreaking routine if it can eat whenever it likes.
