It is caused by the sphincter muscle at the top of the stomach not closing all the way. Older dogs(and people) tend to produce less acid in their stomach as they age. It is the acidity of the stomach that tells this muscle to contract. Many people have had great success with adding apple cider vinegar to their dogs meals, 1/2 teaspoon per cup of food. Using Bragg’s or some other ACV that still has the mother in it adds other benefits as well.
