Does your pup like the food you are feeding her?
I have heard that switching ever so often would be alright. I was caught up in the food research & what to feed them frenzie for a while. But have finally chilled & settled on a good food that they like to eat. Now I'm not going to worry about it for a long time.
The place where I get my food carries Orijen also. They seem to think it's a great food.
