Thanks

Yeah a couple of days switch sounds good when rotating .Better safe than sorry. I never knew you could rotate I just figured they ate what they ate , I never thought of them getting bored
With this initial switch ( to either BB or NV) I plan on doing it
very slow ( over about 14 days) Sydney didn't do well last time I tried to switch her because I think I did it to fast...she was sick with diarrhea and vomiting for over a week and a half or longer ( I think she may of also had some problems from a rawhide) and we had to put her back on her old food.
I want to make sure she doesn't go through all that upset again...so we are going at a snails pace to switch her. We put her back on Beneful ( crap

) and it is ssoooo full of junk that I think her body may reacted harshly to the good food so the slower the better I think..
Thank you very much!! I feel much better about all this now and feel I have a direction to go in
