Hmmm, If it were me, I would take the barking as -- go outside See, when I put Jazzie in her crate to sleep, she would bark, I would say, potty? outside potty? I'd take her outside, she would go tinkle. Put her back in, barking, back outside, soon she got the idea that hmm, this only works to get me outside so she gave up.
Even though your puppy seems to know that she goes outside, it takes at least 3 months or longer of repetitive training for them to get it that the house is not their toilet, some dogs take longer. In the books I have read, it states potty training is established within a year, some even argue that the trustworthy state happens at age 2
When you can leave them alone and they won't go in the house
I hope something here can be useful to aid your little girl to stop her behavior, sometimes a trainer will allow you to ask a question & offer a solution. Best of luck.
