I'm shocked that the pound let her go. But all the better she'd developed weird habits if left there. You can start training her now if you want. Simple things like sitting for food and no biting people. It be a good idea. Her mom would have taught her her to play nice and other good things. You have to do it now. I'd give her a stuffed animal to sleep with. Only if she wont chew it. If she chews take it away at once. You can give her the first shot of parvo instead of taking her to the vet. Make sure you are not the only one who cares for her. Separation anxiety is no joke. It's much easier to prevent then to fix. That's probably more info then you wanted. So i'll stop typing now. Have fun and enjoy her.
