Hi again. I think doggie daycare could be good for her, and yes thay often will behave differently away from thier "pack". Just be sure to apprise the daycare folks of your concerns so they can manage it. Same with the Rotties. You want good , stable dogs that will gently correct her but not go overboard

I would avoid intact dogs unless they are very calm.Of course you also need to get to the point where she behaves when you are there. That is where the leadership comes in. Have you thought about doing some obedience with her, as well as practicing NILIF? With my feisty girl this really helped me to teach her how to behave around other dogs and mind her business when I wanted her to. And , yes, separate time for the dogs is always a good idea. Good luck and keep me posted
