Over the winter, I had 3 or 4 different bags open at any given time and I switched kibbles every day, as well as raw. Right now I’m switching between 2 bags, one week on, one week off. I use Brothers, Earthborn holistic Grain Free, Nature’s Variety Instinct, and I hope soon to also use Nature’s Logic. My dog does best on the Brothers so that is like my fall back food. Right now I’m feeding Brothers Turkey and Earthborn Great Plains Feast, a few weeks ago it was NVI Rabbit and Brothers Beef. As I run out of one thing, I rotate in some thing different. You can rotate however works for you, but I think you should change brands at least every 3 months. That way if one is high or low in something, your dog will only get that extreme for 3 months before you change. I do rotate through a brands different formulas, if they are within the parameters that I need for dog food, but not necessarily one after the other. And I keep looking for new brands to try.
