Welcome to YT!!! I'm sure you'll get alot of great info here, I know I have. Don't really have much advice, other then be patient and consistent, have the puppy on a schedule and follow it. I know it seems endless, but it is definately worth it. My little guy, Winston is 3 years old, and I can't remember when he wasn't "trained". I was told when I first got him, to take him outside directly,wait as long as it takes, and it may take awhile, but when he does finally go potty, praise him, and I mean really make a BIG deal out of it. Then and only then, take him in the house...it worked for me.
Hope I helped even if only alittle.
