I know people say Don't worry, it's hard not to right? The only thing I know for sure is that you are a wonderful mother to your furbaby. You took your Yorkie staright to the vet. A mother that doesn't care would not do this. You feeling miserable isn't going to help, just be there for your baby now. Give her all your love. You had an accident. No one is Perfect. Remember that.I'm sure she forgot all about it, so don't beat yourself up....
