until the puppy is housebroken make sure you tell everyone in the house when they take puppy outisde they do not play with him. Outside is potty business.
Let him do his business, bring him back in the house for a few minutes...then take him out to play. Many times what happens is the puppy goes out, whoever takes him out starts playing with the puppy and then brings puppy back inside and forgot that the puppy didn't go to the bathroom. Like a kid being potty trained, the puppy gets so excited to play they *forget* to go.
