I always go by rule of thumb on an eight week old pup.  1.5 cups in the am, 1.5 in the afternoon and 1.5 in the pm.    Then adjust according to weight as they are growing.  Usually after they reach 6 months, I cut them back to two meals a day, 1.5 in am, 1.5 in the PM, again adjusting to the way they look.  If they are excercising or getting more play, I up the food a bit.  

Good Luck.
