Try adding a little Apple Cider Vinegar(make sure it has the mother in it) to her meals, about a half teaspoon per cup of food mixed with a little water. Seniors often don’t produce enough stomach acid on their own to signal the sphincter muscle at the top of the stomach to close all the way(humans and dogs both), so they get acid reflux. Then they are treated with acid reducers, which just compounds the problem rather than fixing it.
