The following all depends on what issues she had but you might check into D-Mannose powder. It is a supplement that pets can take. I have a family member who is completely disabled and it was recommended by the Christopher Reeves Foundation for UTI's. It has helped her tremendously. My cat is on prescription food because he became completely blocked and can only have wet food. I can give him non-prescription canned and do occasionally but it has to be low carb as it is the low moisture content that will otherwise mess him up. No more dry food for him. The vet said I can give him the prescription dry food but why would I do that if low moisture is a problem. That makes no sense to me. I gave him d-mannose for a while until we got his diet straightenend out. Sorry this wasn't dog specific but I thought I would pass it on.
