The answer to your question is that only you can know, by putting your hands on the dog and examine him to see how his weight FEELS. You should be able to easily palpate his ribs and hips, but he should not be overtly bony.
Adjust his food accordingly, up if he's too skinny, down if he's too heavy, the same if he's just right!
3 cups sounds like a lot of food for a 30 pound dog, but its possible he really needs that much. Sometimes big meals can contribute to loose poo. What brand of food are you feeding him? The type of food also affects the amount and consistency of the poop.
