I don't really know what you mean, American labs don't have any sort of genetics that tells them to stop eating. If they were in a room filled with food they would eat it all, only taking breaks to sleep. I have a lab mix and he shamelessly steals food from our young kids and off the kitchen counter as we eat in the very visible room next to it. He's eaten whole loaves of bread (multiple times), an entire pound of deep fried egg rolls, trays of cookies on and on and on. He's a good boy though.
