And even if it doesnt kill the pup, think about all the eggs that pup is shedding into the environment. The AAVP, CDC, CAPC all recommend starting a deworming schedule at 2 weeks old. Where they differ is on whether it should be weekly or bi-weekly and up til what age, 8 or 12 wks, before you go monthly. The schedule I have on here is there original recommendations. Now an older pup or dog, you are right, does not need weekly dewormings. But for the newborn, there are many many kennels that could tell you very sad stories when they overlooked deworming<img src="http://pitbullsocial.com/file/pic/emoticon/default/unhappy.png" alt="Unhappy" title="Unhappy" class="v_middle" /> Obviously if you know for sure your pup and female does not have any worms because of weekly fecal floats then you have no need to follow the schedule. But if you dont know, this is truly something I consider better to be safe than sorry.
Really you should start deworming the mother before the puppies are born the puppies will get the medicine within her. And you should also give the mother deworming medicine a few days after birth and then start deworming each pup every month
