Friend, your vet suspected Billious Vomiting as he was vomiting in the morning. But, if he is vomiting food now we need to suspect that there could be a different cause. You see, vomiting can be caused by either primary problems in the gastrointestinal tract or secondary to a systemic disease. Common causes are: A simple gastritis, ingestion of a foreign body, infections, parasites, etc.
I am going to make some recommendations below, if he continues to vomit after doing the below recommendations I would have him re-checked by family vet. Discuss with your vet about doing xrays as initial screening test. In the meantime this is what you can do:
1- Do not give things like Pepto Bismol or imodium. Start him on Pepcid AC (famotidine) 10mg tablet every 12 hours. You can buy Pepcid AC over the counter in any pharmacy.
2- No food or water for 8-12 hours. Need to give his gastrointestinal tract time to rest.
3- After 8-12 hours offer a small amount of water. Wait half hour, if no vomiting, offer small amount of rice (50%) and boiled boneless chicken or ground beef (50%) 4-6 times a day. Keep on this diet for several days then wean into regular diet.
4- If he continues to vomit after doing the above he will need to be seen by your family veterinarian for a hands on examination, xrays and fecal analysis as initial screening test.
