We are getting better. Only one accident yesterday but I think that was because my husband was paying more attention to his computer than to her! Today I was napping on the couch (ok, I fell asleep for about 3 hours) and she wasn't tied to the couch as usual. I woke to the lite jingle of her tags and her laying on the floor looking at me like, "Will you wake up, Pleeeeeeeeeeeeeze! I've got to go!" I gave her the handsignal for potty/walk, she hopped up and went straight for the door. YEAH!!! When we came back in, I check all over and I haven't found a puddle yet!!!
Do you have an area where you can block her off to the rest of the house. Bathroom, Laundery room? or if you have a little pen. Put her in there with her bed/crate, food and water and piddle pad to the other side. She wont go where she eats and sleeps. After a week give her a bigger area. If she messes up, make it smaller again. She'll learn.
If we have been playing in the house, I will take Katie out right afterward so she can pee. Then I come back in and set the timer for an hour of quieter time, bone chewing, napping etc. When the bell goes off we take a short walk. If she does both of her deeds then we will take a bit of a longer walk. Slowly but surely she is getting it.
