Hi Sabema, ask your specialist can he prescribe some 20mg Omeprazole (Losec) its a stronger ant acid then Pepcid, its given daily, 1 hour before food & last 24 hrs, also is he on a low fat diet, as high fat diets can cause bad acid reflux, I hope your specialist helps this time cause 4 years is a long time like my Patch…. I finally had an Endoscope + Biopsies done, 1 month ago & Patch has “moderate to chronic Lymphocytic Gastritis with associated spiral bacteria infection” (Helicobacter infection)…he was gulping & swollowing at night with bad acid reflux, heartburn, sometimes vomiting & feeling nauseous… make sure if you do have an Endoscope done that you get biopsies as well cause when my vet did Patches Endoscope everything looked good visually then 5 days later I got the results from biopsies.. With my last dog, I just had a endoscope done & like Patch everything looked good, I wish I had gotten biopsies done but I didn’t have a computer back then, to google info & join groups to find out what other people were doing..
Good-Luck with Tucker, once you get a diagnoses you’ll feel so much better cause the illness can be treated with the proper meds, An Endoscope + biopsies is best.. with an Ultra Scan you can’t see inside their stomach, I just wasted $450 having an ultra Scan done..
