I like to keep them on a new food longer, so that I know for sure my one dog is doing fine on it. I start with a small bag, in case he doesn’t react well, and then another. I go for 3 weeks on a new food. If he hasn’t reacted by then, I’m not worried. If he does react, I just give the food to the other 2 dogs. I’ve never had him react to a food that I didn’t know within the first bag, but the last food he reacted to took much longer than any other food has.
