Don't decide a name already..... Wait until you get her to see what her personality is like. Try a few out. See what she responds to best.

If you got rid of your past dog because of behavourial problems that you guys couldn't fix, what makes you think this dog won't develop any? You can't just dispose of a dog because they have behavourial problems. You are the owners and you are responsible for care and training of your dog.

I hate people who just get rid of a pet because they can't handle it or don't want it anymore.
