Holy *bleep*! Rayden would be getting almost 9 cups of food a day! Of course, if he was eating cheap store brand food, then he'd NEED that much.I'm not an expert by any means. But I do know that it does depend on the weight of your dog. When I was feeding kibble, my vet said 1 cup per 10 lbs.
As it is, he eats 4 cups a day, with some eggs/cottage cheese/what not added in on occasion.
