Hello I am Dr. Joey. Thanks for trusting me to help you and your pet today. I am a licensed veterinarian with over 15 years of experience. I look forward to working with you.
I too am quite worried about your dog. I want to confirm that your veterinarian did more than just give him medication. Did he already have complete lab work that included a complete blood count, chemistry profile and urinalysis. And did he have radiographs (X-rays)? These are all critical, given his issues to determine what is going on.
I also need to confirm is he actually regurgitating or is he vomiting. BIG difference. If he is actually regurgitating which means there is no actual heaving associated with the stuff that comes up - he really just opens his mouth and it all reappears, then this points to an esophageal problem such as megaesophagus or other abnormality with the esophagus. This is critical he have chest X-rays reviewed by a board certified radiologist immediately. There is potential treatment for this but it can sometimes be very tough to contend with. He would also be at high risk for pneumonia.
Alternatively, and this sounds more likely, he actually is vomiting. This could be due to a long list of potential problems ranging from primary stomach
issue (foreign object in stomach, ulceration, tumor, infection, etc) to organ issue (liver, kidney) to pancreatitis
to inflammatory bowel disease to cancer and the list continues. IT really will require the testing mentioned above. If that was already done and he has been given super anti-vomtiing medications which are not working (and we are sure this is a vomit and not a regurgitation) then this requires a next step of endoscopy or surgical exploratory to look at the stomach and get a biopsy. This usually will get our answer.
I am at a point I need to know what questions you have. We can continue our dialogue in this setting.
I hope that the information I provided has been helpful.
