Six weeks is very young for such a small breed. What kind of set-up do you have for her while training?
The easiest way to house train a puppy, whether to go outdoors or on paper/puppy pads, is to know when a puppy needs to go potty. Generally then need to go when they wake up, after they eat, after they drink, after they play, before they sleep, etc. Often times a puppy will play-play-play, then once things calm down, they will have a bowel movement.
When I train puppies, not only do I use crate training, I gate the puppy in the kitchen UNLESS he can be ON LEASH with me on the carpet. So, unless I can pay 100% undivided attention to the puppy, the puppy is not on my carpet - period.
Puppies can't control their bladders/bowels until 12 to 24 weeks of age. No two puppies are alike. In my last litter, I had one family swear their puppy was house trained by 10 weeks of age, and they were devastated when at 4 months he had an accident in the livingroom
. I had more knowledgeable puppy people know that accidents can happen anytime. Even adult dogs will have rare accidents in the case of illness, etc.
As for other obedience commands, your puppy is only six weeks old. That is very, very young. Spend a lot of time playing with her, "yelping" if she nips too hard, making sure she gets to her paper when play stops, etc. Find a good trainer and get her ready to start classes at about the 10 week stage. Have people come over to meet her. Start her socialization now.
