I agree with the others, but will add that may be she is getting dominant.
When our Molly was a pup I was always threatening to have her put to sleep, she was h*ll to live with! She used to jump on the furniture, and she wasn't allowed. She wouldn't get off when told, and if you went to get her off she would bite your hands. She was one dominant female I can tell you!!
After talking to her breeder, I realised that she was testing us to see who was boss, and I decided I was! When ever she was naughty I didn't speak to her, but I got hold of her collar and dragged her out of the room... Even if she tried to bite me. She had to stay out of the room for a minimum of 2 minutes. If she started acting up when she was let back in she was dragged out again. She soon learnt that when she did things we didn't like that she was turfed out of the room.
We never had problems with her using the house as a toilet though, so i can only suggest as others have said, you will have to start at the beginning again... She is still a baby at 4 months
Honey is the one in our house who used to jump up on the work surfaces. Luckily for me, after her getting a few sharp NO's, while I pushed her off and pulled and angry face, she has stopped doing it.
And to make you feel so much better, Molly changed into a much nicer dog after her 3rd birthday... So you haven't got too long to wait, lol!
