Lethargy and no appetite
Isobel, vomiting can be caused by many different conditions that affect dogs. It will be difficult for me to determine the exact underlying cause without a hands on examination and some testing. But, common causes are: A simple gastritis, dietary indiscretion, ingestion of a foreign body, infections, pancreatitis, etc. to name a few causes. His lack of appetite is most likely related to not feeling well from what ever is causing him to vomit. If he is panting on and off this could be an indication of things like: A fever, pain, etc. which could also cause him to vomit.
In this case, I would strongly recommend a hands on examination with family veterinarian to determine the exact underlying cause. In the meantime, this is what you can do:
1- Do not give things like Pepto Bismol or imodium. Start hims on Zantac (ranitidine) 75mg 1/2 tablet every 12 hours. You can buy Zantac over the counter in any pharmacy.
2- No food or water for 4-6 hours. Need to give his gastrointestinal tract time to rest. I know you are concern about dehydration. But, we need to give his GI time to rest so that when you do offer food or water he is able to absorb it without vomiting.
3- After 4-6 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- Follow up with your family veterinarian for a hands on examination.
