Hi Rita,
I really think your dog is having bad acid reflux attack & it’s bad, it is definitely something to do with his Intestinal tract, not the brain, don’t bother with the Ultra Scan, the Ultra Scan can’t see inside the stomach, he needs an Endoscope + Biopsies done, biopsies can give vet so many more answers, next time this happens have some liquid Mylanta in the fridge ready & waiting, when the Mylanta is kept in the fridge it keeps it cold & it cools the esophagus down to the stomach & gives more relief, make sure you shake bottle & give about 5ml, 1 teaspoon, the Mylanta can not cause any harm, if anything the symptoms will all stop & you will have your answer to what is causing this problem….I never recommend Pepto Bismol as it has aspirin in it… but people do use on dogs, Pepto Bismol has been banned in Australia cause of the Aspirin…
I would not try the Prozac, cause this is not something happening everyday, it seems to be Gi related, also when this is happening have you offered a dry human biscuit or dry white bread toast works great…
