Congrats on your new baby!!! How exciting!
I know a lot of people who wee pad train their dogs, but I believe in potty outside. Here's some info on some different house training methods to help you decide what you want to do:
LDT House Training
My preferred method of house training is crate training, which keeps your pup and your home safe from chewing and other dangers.
I have met a lot of people (I'm a trainer/behaviorist) that started off with successful paper/pad training, and then the dog suddenly avoided the pad, and wound up using the whole house as it's personal potty.
I do suggest also keeping the pup on collar with the leash attached to your belt loop while he is not crated. This will allow you to have total control over the pup, and you will know when he needs to potty.
If you have any training/behavior questions about your new pup, please don't hesitate to pm me and I will gladly help you out!
Good luck and congrats!
