I honestly wouldn’t agree about adding rice in. It is considered a “filler” food and provides little-to-no nutritional value to a dog. That’s something that’ll go right through her stomach and contribute to more frequent/bigger stools, really. I’d definitely say I agree with crazy4cats. This site can help out a lot with finding a limited ingredient super-quality food for her.
Possibly to reduce fillers even further and get a protein boost you could add in your own raw meats to her food?
