As mom to a "big-boned" boy (Lightning), I've fought for years to keep his weight down. I tried Nutro Lite, which I loved, but it seemed to leave him feeling ravenously hungry (to the point where he would go outside and eat his poop). He also wolfs his food. So what I do now, and what seems to really be working well, is I give him regular food, but less of it, and I add water to it. Not only does it slow him down, but I think the water makes him feel full-ish. It's apple season here, and he LOVES apples. He'll eat four or five night. I've noticed that with our new eating plan, he's not eating as many apples. Hence, maybe he's feeling full? And he looks fabulous.
