I would start with feeding one or the other of the ToTW for a week. She already eats it so it would not be a change but it could help you narrow down if one formula or the other is a problem.
Dr Tims and Victor both have some quality formulas that might be options to switch to. I run from "senior" foods-- seniors need more protein, not less so I agree with you on that for sure.
I'd probably stop (after trying formula only at a time) supplements and most treats for a week each. Like, drop one and watch for changes.
Also check labels and reviews to make sure no manufacturer changed ingredients or proportions without making it known
Have you tried the old standby of canned pumpkin?
