You can add us to the ranks.....2 weeks ago Ozzy started peeing on the floor after being 99% pad trained. He's 5 months old. I have no idea why either. I can't go one day without a pee accident. The poo well he still hits the pad for that so I have something to be grateful for.
We are back to Potty 101 but I still can't catch him all the time as he will go hide and pee! I keep saying this too shall pass...this too shall pass..
