Breaking the habbit??

You need to keep her off the bed. That could mean using a baby gate to keep her out of your room. As for the rest of potty training, train her as you would any other dog. Feed her on a schedule so that she will relieve herself on a schedule. If she is on a schedule it's easier for the human to be trained to it. Once you know how long it takes for her to poop after eating (think about 30 minutes), you can play with her in the general area of the paper (try using a litter box), and place her on the paper when she starts circling or sniffing or giving you other potty signals. Since you are keeping little treats in your pocket, you will be able to give her a treat the instant she is done. Praise also.

My preference would be to have her sit at the door, then carry her downstairs, then walk her to the potty area. Again, treat and praise the instant she is done. If she HAS to go, she will go. She can only hold it for so long.

You don't write what you are feeding her, but if she is on a low quality diet she will need to potty more often.

I agree with Maura's advice. I just wanted to add that you canNOT punish your puppy for pottying on your bed. She's doing it because she thinks it's the right thing to do, and it's your job to prevent her from making mistakes.
