I would try digestive enzymes. She may not be making enough of them on her own. Strong smelling gas is one sign that proteins are fermenting in her colon instead of being digested. Allowing access to a dish of food all day does not encourage a dog to go ahead and eat. I would much rather add a spoonful of yogurt or something that will encourage the dog to go ahead and eat than leave food down all the time.
