Mine moved to 1 cup 3x a day at about 9 or 10 weeks, I think, but if I can remember way back to when we first got Mulder, I think he came home on 1 cup 3x a day. The problem with Labs of any age is that they are ALWAYS hungry and searching for food, even if they are being fed an appropriate amounts. You could try upping his food a bit to see if that helps, but he may never appear satiated, LOL.
