Hello and thank you for the question.
Is there any chance he got into any toxic substances?
When was did he last defecate?
Any change in diet?
Ok, Thank you for that information.
It is possible he ate something that has caused a mild irritation of the intestinal tract., You can give Pepcid AC to lower the acid in the stomach.Here is a link to the recommended dosage for dogs.

I would try to feed him a bland diet for the next 2 days. Boiled chicken and rice is recommended. Was the chicken after boiling to remove all fat and grease. Feed this in small meals several times a day.
He may be wobbly from a drop in the blood glucose cause by not eating. Karo or pancake syrup can be rubbed on the gums to help him feel better.
If the vomiting continues, blood appears in the vomit, or becomes more lethargic I would have him seen right away.
I hope your fur baby feels better.
Please let me know how he is doing tomorrow, or reply back if you need further assistance tonight.
