Q. My dog regergatates his food since 4 months old about once a week he is 5yrs old now. He is a Shih Tzu. Picky eater licks lips all the time.Vet no dx

A. If an Xray has not been performed that would be the first thing to suggest as chronic regurgitation could be caused by a condition called "megaesophagus" which is an abnormal enlargement of the esophageal tube.

If he licks his lips it might be a case of chronic nausea causing vomiting and not regurgitations. In that case I would suspect pancreatic disease (EPI, pancreatitis) or IBD (inflammatory bowel disease). A specific blood test can be done for pancreatic problems.
