Hi again,
I sent you a pm on your other question. And I just read your new post where you said you'd already tried putting some of the poo on the paper. If she is eating it, it's called Coprophagia and is really common in puppies. There are several reasons for it. One is something missing in the diet, but I'm sure that's not the case with your Megan. My older dog did that when he was a puppy. Here's a link to some info on it....
http://perfectpaws.com/copro.html. There are several products you can buy at the petstore to stop that. Just search on coprophagia (or "eating feces").
Just don't get in a hurry and don't get frustrated. It will seem like a long time during it. But if you stick with it, you'll have over 10 years of a wonderful life with your Megan without having to worry about housebreaking!!
Good luck and keep everyone posted.
