Please help! We got a new puppy (11 weeks old) I'm the one that wrote the other day about him being 7 pounds!

Well we've always had large dogs, dobermans and he is so much different! I just wanted any new puppy advice that I might need to know!

He's fun though! And he's fast and I think he thinks he's big b/c he jumps off the arm of the couch and I'm freaking out, but it doesn't even phase him.
Also I take him out constantly and it never fails he will sneak onto the carpet and pee!!

But never on the tile!
Is there anything else I can do to speed up the potty training process? I keep a constant eye on him and tell him no when I see that he pees, I just stress because it's like no matter what I'm doing (cooking, watching tv, laundry) I'm also trying to keep an eye on him!
Please help!
