Thanks everyone. I was worried about Fauna for sometime because as soon as I got her I took her home and gave her a bath, or 5, because she was in such bad shape. Her white fur was brown and she had blood washing off her body from the fleas. But now she is doing much better, although she does still nap a lot but I'm beginning to think that's just her style. She clearly has the right idea on how to live life. But, I've tried lots of things with Pumpkin and we had a trainer for a couple of months that really turned her around. She no longer bullies puppies or chases children when they run, but she does tend to play a little too rough for my tastes, but we are working on that. Fauna likes to chase squirrels and herd which is making Pumpkin pick up old bad habits. Pumpkin has a Chuck-It that she is obsessed with so that seems to be working out for her. Fauna however I have to go grab her every know and that at the park because she plays rough as well. So when they both get together we're pretty much the terrors of the dog park.

Well, just take it one day at a time. Maybe as they get a little older they will learn that herding small groups of children is not socially acceptable behavior.
