Ok, I must have bragged way too much. Lilly has always been really good about using her potty pad

. Usually TOO good. She would pee a little here and there ALWAYS ON THE PAD THOUGH every 10 minutes just so she could get a treat

. She had it down pat. She'd look at me, then my bf, then she'd walk to the pad, squat, pee or force pee then look back at us waiting for a treat.
Great!
Until now. For the past several days she hasn't used her potty pad but ONCE

. I have cleaned up so much pee

I could scream. Then today! She pees on my flippin' couch! I was sooo upset. I told her "NO!" "BAD GIRL

" and she was gated in the bathroom with the door shut for around a hour. Before when she would pee I would tell her "NO!" "BAD BAD GIRL!" and ignore her for about 5 minutes.
Bad thing about it is SHE KNEW she was doing wrong! She knew it! I know this because she would pee, smell it then see me getting up to scold her and she'd run upstairs

to hide from me. I've even tried telling her no, bad girl and then setting her on her pee pad and patting on the pad and telling her "THIS IS A GOOD GIRL!!!!!"
I'm looking for any advice anyone can give me

, it's getting out of hand and I've transferred way too many rags into pee rags over the past few days.
I feel like everything I've taught her as far as potty training has went out the window. It upsets me so much that she knows where she's supposed to potty but she isn't doing it.
