How many times have I been through this? counted them--7. These are my experiences:
Forget the newspapers, you'll just have to re-train your pup!
The best thing, I have found is the crate method, since the pup is unlikely to soil its sleeping area. Be sure the crate is not too large, or it will sleep in one area and use the other area as a bathroom.
Take your puppy outside, to the designated bathroom spot, first thing in the morning--that means even before you go.
Then 15 minutes or so after every meal, nap, and make sure they pee and poop before bed. Be sure to praise the pup for doing its jobs. It also helps to withhold water a couple of hours before bed time.
When the pup is older, (maybe loose in the house) and shows signs of going to the door to want to go out, hang a bell from the doorknob at the level of your pup, so it will bang against the bell and you will hear this, and can let them out, but do so immediately!
Remember that the pup's sphincter muscles are not fully developed until about half a year of age, so don't expect perfection in this area until that time. I'm sure there are other tricks for potty training, but these have helped for me!
P.S. I've trained my dogs to "go on command". It is really helpful when you're in a hurry!
