Hi Cathy M-
It sounds like switching foods would be a great idea for multiple reasons. Here is a link about a diet rotation: /frequently-asked-questions/diet-rotation-for-dogs/
I feed my lab/retriever mix dogs a couple of different kibbles with either canned, fresh or frozen mixed in every meal.
So far our favorite kibbles are Victor grain free, California Natural, and Eagle Pack. Since it sounds like you have been feeding the same food for a while, you will need to do a slow transition to the new so make sure you start it before the bag of Blue gets too low!
Which flavor of Blue Wilderness are you feeding her currently?
