so so happy you saw her and helped her! it seems you did everything right and as for bark, I'm sure we can point a thing or 2 that we did ourselves and we shouldn't have. what happened is in the past, you learned for it, it all that matters.
she should be fine now, but I'm sure the stomach did go out but not the whole way and she fixed it herself by swallowing. of course the damage might have happened, but their stomach can stretch a lot, hopefully it is all good. I would soak her in melafix once a day for a week just in case of any bacterial infection is happening. yes not feeding for a few days is good idea, give it time to heal itself and when you're back to feeding don't do big amounts at a time.
