Phillip, as I understand it there are several reasons to do a rotation diet. One is for variety for the dog, flavor-wise. Another reason is to give the dog different ingredients in the food. Every food has different basic ingredients, some have oats, rice, peas, etc. , something to help bind the food to keep a kibble shape. Also different supplements in varying amounts. By rotating the foods the dog gets a variety of all these things, not too much or too little of any one thing. For example, rice is known to contain arsenic (absorbed from the soil it’s grown in). A little is not harmful but if your dog food was always the same thing, like a turkey and brown rice variety, he could potentially build up too much arsenic in his body. By doing a rotation diet, you’d avoid that kind of thing. Another point , if you find several foods that your dog does well on, you can take advantage of sales and save a few dollars now and then.
