Change your locks and watch your bank accounts/credit cards. Also take look at any interesting collections you and dc's might have -- playmobile charactors, coins, fossils etc. These people knew no boundaries in your home and obviously were everywhere for hours. I am paranoid, I know, but this was weird. I can't imagine behaving like that at home in anyone elses home. Not even our best friends home where yes we do know where most things are -- I would have brought paper towels from my home rather then search!
I probably would never say a thing to them. I would try to never say much to them again-- too bad they live near by. Because they seem to be nuts and appear to be clueless about appropriate actions. I wouldn't want to be on their bad side.
Just say friends are taking care of dog at their house if ever asked why not hiring again. You have no responsibility to parent their daughter -- the fact she is not hired again is plenty.
