I don't have any personal experiece, but I believe patience and consistancy are the biggest key!! She's only 11wks, so consistantly bring her out to potty every hour. If there's a time you can't keep an eye on her for a moment, put her in a confined area, such as a crate, so she cannot soil. Be patient..she'll catch on. Be sure to clean the area where the accident was very well, so she won't be inclined to potty in that spot again.
Hope that helps..There are some here who can probably help you much better!!
Good Luck, and welcome to YT!
