Sounds like you got wonderful advice!
I had a similar situation with Taycie as well. I was crate training and about 16 weeks I felt it went out the window. She would pee on her blankets... Thankfully never poop
But even if her crate was open she would go in there and pee!
Needless to say I had one VERY confused puppy
.. You see, I was taking her outside during the day at work and at home I was using puppy pads. She would do WONDERFUL at work and then at home I had issues. So after some long hard reading this is what I did.
The x-pen, play pen is wonderful advice! This saved my butt! I set this up in my room with a dog bed and toys on one side then her potty area on the other. I also keep water in her xpen.. alot of the reading material advised no water during potty training but I have different feelings on that subject.
I then decided to get rid of the puppy pads because that was what she did not like, and seemed like the problem causer. SO my solution to this was plant a sod box! I just bought an under the bed container and drilled holes in the bottom for water. I added some soil and cut a piece of sod to fit. The entire thing cost me 10 BUCKS and was a major livesaver
With in a week she was 95% back on track. She is now almost 10 months old and I NEVER have accidents. She will scratch on the door or stand on my back and growl now.. she is doing fantastic
I also washed everything in her crate with urine out and laundry detergent on HOT.. sometimes they can still smell it even if you can't and bleached her entire crate. Dogs will pee if they can smell it.. no matter what
I also did take her blankets out of her crate for a few days, I know this may seem sad but this helped a ton because her blankets were absorbing the urine. The minute she peed in her crate without blankets, actually happened when we where driving. There was not alot I could do until I got home, but she cried and cried and cried. OH how she hated standing in her pee with NO blanket. The minute I got her home I bathed her and a few weeks later I did add her blankets back.. she has NEVER peed in her crate since!
I would also try schedule feedings if you dont already. That helped me a ton too! I hope this helps
