Another week

I've decided to keep Bambi for another week. Im hoping it will help him get used to people though i'm guessing one week will not be enough. He's a good dog but it is a bit frustrating - he's afraid of everything and at home he just lies on a pillow and barely moves. He cringes or runs away when I get close to him and it is hard for me to get attached - which I guess is a good thing because I really don't need another pet!
