Don't give up yet there's still hope...I have a maltese/yorkie mix that is 7 years old and just got a yorkie about 3 months ago that was 4 months..Peanut always had a problem with going in the house alot, drove me crazy, I would take him out and as soon as we came in he would go..Sometimes I think he did it to see how far he could push me, anyway when I got Lexie she started using puppy pads, so did peanut, and when Lexie goes outside I make it a big deal to tell her what a big girl she is, so now Peanut is doing it to and waits to hear me tell him the same.. what I am trying to say is maybe she will do what he does and praise him, make a big deal about it and then she will want the same..I swear I think it is a yorkie thing....
