Gosh that sounds just like almost 14 year old Wink except she has all her teeth. She had totally lost interest in kibble so have been making her a slop of meat/rice/pasta/veggies, whatever. She has recently started to eat kibble again so I am mixing the slop with the kibble. When she was being really picky I would actually hand feed her and that seemed to work, don't know why? Sometimes I think it's her tongue not working correctly - sort of like she had a mini stroke or something, but then other times she has no problem.
She whines and barks for no apparent reason most of the time. I blame it all on the "old crazies".
