My puppy was playing on the couch and when he jumped off he hit the coffee table barked  was is not hurt. He has vomited 5 times in the past 2 hours ,the first thing he vomited was his puppy treat .We did feed him some bread from the table,I dont know if he is vomiting from the fall,or if he over ate or if he he is catching a cold beacuse evryone in the house is sick. Please help ,I will bring him to vet in the morning.

Chi's skulls can be slow in closing the fontonelle, which makes them vulnerable to head injuries.  Hopefully you will be seeing a vet first thing.
