Adding fiber is one of my suggestion discussed below, I would not add to the water, this may make him not want to drink and unless he is drinking the whole bowl he is not getting enough.
Ok, Most of what you are doing is right but there are some things that need to be adjusted.
The absolute first thing I would suggest is asking your vet to test for a liver shunt. This is very common in this breed and we almost always see it is the small pups(as this effects growth). This also causing vomiting and intermittent loose stool. This can be worse after eating as this is when the toxins are highest in the body, when the eat they feel bad so they try to avoid eating. Researchers at Cornell University College of Veterinary Medicine are actually researching the gene mutation in this breed that leads to Liver Shunts.

These dogs should be eating 4 times per day, when they go to long without food acid builds in the stomach resulting in nausea refusing to eat.At 1 year of age they can go to three times per day. I would also try using the Pepcid daily for 7 days and see if that makes a difference. Give this on an empty stomach 30 minutes before offering food. This medication needs an acidic environment to work properly.
Always use a plate most of these dogs will not eat out of a bowl. The mouth and nose form a straight line in this breed and often eating out of a bowl allows the nose to come in contact with the food.
I know you are having trouble getting him to eat but right now he is not getting a balanced diet and is not providing enough fiber in the diet to regulate the stool.
I would like to you try a good quality dry food.I highly recommend Royal Canin 24. This is a Shih-Tzu specific food (even shaped for easy pickup)
I am going to give you a link to this food scroll down to and click on the Shih-Tzu guide you will see that this company has done extensive studies into the dietary needs of this breed.They have this in puppy as well
I know you are just making sure he will eat but I can promise you the longer he eats only human foods the less likely you will ever get him to eat dog food.
Mix the dry food 1/4 day 3/4 boiled chicXXXXX XXXXXver, ground chicken or turkey. This must be boiled to remove all fat or it too will cause stomach upset and diarrhea. Over a 4 week period slowly remove the human food and add more dog food. You can always add a small amount of the meat it just needs to be mostly dog food. Adding low sodium chicken or beef broth may also make it more appealing and soften the food if he prefers it that way.
To the food you also want to add 1/8 teaspoon of metamucil once daily to add fiber to the diet. Another way to add fiber is with canned pumpkin(not pie filling) this can be frozen in an ice cube tray and given 1 cube daily as a treat.
The probiotics should also be used daily.
I would suggest discussing the possibility of a liver shunt with your vet, have x-rays of the abdomen to be sure there are no abnormalities which is also common in the tea cups. When these dogs are breed down in size it is the body that is scaled down not the internal organs and we often see digestive trouble in these dogs. Change the feeding to 4 times per day add fiber and ask about using the Pepcid daily.
I would try the above things and I really think you will see a difference. Please let me know how he is doing, please reply back if you have additional questions or concerns.
