Why Does My Shih Tzu Eat Grass? Can Shih Tzu Eat Grass?

Experts are not 100 % sure why dogs eat grass. It is safe to assume that Shih Tzus exhibit this behavior for different reasons. The theory is that canines evolved as omnivores and would eat whatever was available, including vegetation and the stomach contents of their herbivore prey. So far it is assumed that grass eating is not done by dogs as a form of self-medication.
