Based on that history and your dog's age I would be concerned about something more serious going on than simple gastritis. His symptoms could be due to a metabolic disease like Diabetes, kidney failure, pancreatitis, toxin exposure as well as intestinal disease like an obstruction. With the lethargy he could be dehydrated and/or in pain and need further care. I recommend you have your veterinarian examine Barney as soon as possible.
