If she was locked in a garage I'm assuming she wasn't really ever allowed in the house, so there's probably some anxiety about that, she's probably expecting to get in trouble. Crating might help relieve some of that by giving her a safe, cozy place when she feels overwhelmed. As for the eating, she'll come around, I'm sure. Are you still trying to feed her the ol roy? My mother attempted to give her dogs that and they just about starved themselves before she figured out they were never going to eat it. These dogs eat their own poop but refused that crap. She put a bowl of 4health chicken & rice (what I feed) in front of them and they devoured it, neither of them got sick from the switch because they hadn't really eaten in so long.
