The most important thing is to keep track of each pup's individual weight. You want to see an upward trend in the weights. If one pup is gaining too slowly compared to its littermates, make sure it gets more time on the nipple. Many breeders rotate the pups, so smaller, weaker pups get a better chance to fill their bellies without being pushed off the nipple by the stronger ones.
I don't know of any hard and fast criteria that say a pup should gain x amount of weight per day. Just make sure it IS gaining!
