I’d prob go down to 2% until you can feel ribs again. She is pretty much an adult at this point. She may fill out a tad more. When you have her spayed ask the vet to check to see if she has anything solid feeling in her gut to make sure no instructions have occurred. Be sure the only bones you’re feeding are soft non weight bearing bones. I know some people fast one day a week to let their dogs digestive system empty and reset. You may try that. Is she not eating anything at all for days at a time?? If so I’d be concerned about something else going on. If she’s just eating less I would lessen her food amount.
