The people in Whole Dog Journal recommend rotating dog foods every 2-4 months to avoid allergies and mix up the proteins and vitamins your dog is exposed to. So I was wondering how many people here actually do rotate their dogs food and which brands they rotate among? My puppy eats Innova puppy food but he's never really had what I would call a perfectly 'normal' bm on it. He's always been a little loose and gassy so I was thinking about switching him over to another food anyway. Also, how many here actually use a large breed puppy or dog food on bigger breeds? The one breeder told me to just feed the puppies adult food from 4 months on to prevent them from growing too fast but the vets totally disagree with this and there aren't that many large breed foods out there.
