Well... I certainly understand your frustrations. My deal, is that since day one with Meka (9wks) we decided on the pee pads. So, I use to confine her to a playpen w/ pee pad during the day while I worked. Left the TV on for her and she was fine. She's always use the pad (if confined to one area). So, now at almost a year, we were a little laxed on the training (because she was doing so good) and gave her full run of the house (big mistake)...
None the less, Im having to virtually start over with training her. Im trying to crate train this time, in hopes that might help her with knowing when to use the potty. And this is something I wished I would have done when she was younger.
Also, though she's mainly trained on pee pads, she's always been able to potty when taken on a walk/outside. I think it kinda comes natural for them. Im by far not an expert, and probably haven't helped much, but I hope you get the answers you need
