As long as your dog's stomach can take it.. then I don't think there would be any issues doing so. (I.E. his stools are consistent)
The one thing to keep in mind while 'rotating' is to give a full variety of ingredients, to avoid allergen's forming, etc.. So.. if the first 2-4 ingredients include chicken or turkey, try to get something next time that doesn't have chicken or turkey.
