your food will probably have a suggested amount on the bag for the puppy's weight and age (probably an amount total for the day, so divide into the 3 meals). That is a prettygood guideline... our Sammy is a little skinny since she is growing so fast so our vet said to stay at the higher end of the guide.
What are you feeing your puppy?
and yes, you should pull the food up after 15 mins or so, so the puppy leanrs to eat during mealtime. He is not going to let himself go hungry, so if he doesnt eat much, he will learn very fast to eat if he is hungry! Also puppies go through different period of growth so they may eat and sleep more and less during different weeks of their development. This is normal variation.
