my boy doesnt know when to stop.... he will literally eat and eat untill he pukes it up, so now i feed him once a day.....i put about 1 cup of food (eukanuba small bite maintenance) and then if he wants to eat it all right then and there he will if not then he can snack on it later too..... he eats like a horse....... at first he used to eat it all, but now he eats most of it and leaves a little something to snack on later
