Potty training....Oh will it ever end? When she pees in the house and you clean it up, what do you use? It could be that she smells her previous booboos and thinks she should pee there. I used some stuff called Nature's Miracle that I got at PetCo. It "supposedly" removed the odor from the carpet so they wouldn't keep returning to the same spot. I don't know if it did. I couldn't smell anything but how would I know if Duncan can? He learned very quick. We went out alot and often. I always said "do you have to go outside?" rather than "let's go outside" which I reserved for walks. Also, when he was peeing, I repeated "Hurry up" over and over again. Now he's at the point where if I say Hurry up, he'll pee immediately! It works well, as long as I don't tell my boyfriend to Hurry up! in the house while Duncan is within earshot!
How old is Keegan? She'll get it! Don't fret! Another thing, always go out the same door to pee. Keep a close eye on her inside so you can catch her "in the act", then quickly pick her up and take her out. For months I didn't let Duncan go in another room alone because I didn't know for sure if he had it. I followed him around the house like a nut! I even took him in the bathroom with me in the morning so he wouldn't be in the living room peeing. Now he thinks he has to go with me all the time!
I don't know if this helps. You probably already know all this but...Good Luck! Be grateful that she has 1/2 of it down. #1 is easier to clean up!
