My 17 month old lhasa apso Maggie is driving me crazy! She has started using the bathroom inside again. She did this once before, but it only lasted for a couple of weeks and then she was fine. Well, this has been going on for about a month and a half now. I took her to the vet and they said she was as healthy as could be. I have blocked off most of the house so that the only place she can be is upstairs in the loft and hallway. There is still one place that I can't see her go and that is behind the chair. I have put a box back behind it, and now she just goes anywhere. I take her out every hour, and every time she goes outside I give her a treat. But it seems like she'll come in and then go to the bathroom within 5 minutes. She knows what she is doing is bad because as soon as you say her name (once you've found what she's done) she gets really low to the ground and goes and hides. Does anyone have any suggestions??? Thanks!
