Generally, a puppy should be given an ounce of food per pound of his body weight while an adult Shih Tzu should be given ½ ounce of food per pound of body weight.
Milk & Dairy Safe?
Milk and Dairy. Some dogs enjoy drinking milk, but unfortunately, they are not capable of digesting the lactose in milk and other dairy products. This causes soft stools and watery diarrhea, which is not just a mess but could cause dehydration. To avoid this problem, use lactose-free dairy products for your Shih Tzu.
