Rice is a grain, therefore grain free foods do not have rice in them. Also, while rice does have arsenic in it, it is supposedly not higher than what the body can process every day, HOWEVER, I still don’t want to feed it every day. And if the dog’s diet is the same day in and day out and the food is primarily rice, i.e. cheap dog food, then I definitely don’t want to feed it every day. So this argues for diet rotation. And/or choosing a grain free food.
While dogs do have 2 to 10 times the ability to handle carbs than wolves do, that does not argue for feeding them a primarily carb based diet, 2-10 times next to none is still pretty low.
