Shih Tzu Q&A
he might have allergies, so you may need to change the food he eats until you find one that makes him feel better. You could feed dehydrated raw with a good simple, organic dog food. Take him to the vet and see if giving him a antihistimine would work for him. if you dont help him , he wont get help, he cant help himself. or give him to a rescue so they can help him.
