Edit: The original answer is incorrect. Puppies need stimulation to poop and urinate when they are first born. Typically the mother will lick the puppy to get it to urinate or poop, but if the owner needs to assist then you can use a warm paper towel on their stomach and anus to get them to use the bathroom. This is very important until they can do it on their own, which is about 2 weeks after birth typically.
