I can't understand how people can possibly think that a pit bull terrier and small children go along well. :/
Merlin is a golden retriever and they're among the most gentle dogs you can find. But I wouldn't let any dog alone with small children, no matter if it was a pit bull or a goldie!
And it her screaming at you when it was HER fault? Excuse me?
I hope you buried her deep enough. Seriously.
