I don't think I have any advice for you seeing as how I'm going through the same thing and she's the same age as your puppy. Raisin was doing very well using the pee pads, then I changed to one less pad than before and it's just gotten worse than ever. She also seems to be peeing a lot more than before like yours.
I'm thinking I just have to start all over... keep an eagle eye on her and if she doesn't go when I tell her... put her in the crate for a lil bit, then try to get her to go again when I let her out, and then she can be out and play again till the next potty break... only thing is she seems to be peeing sooo often! Other than that I'm not too sure what to do

I sure hope it works!! I wish you luck with your training!!
