Please help, Lucy, my 8 month bitch was fine in the house training department until a few weeks ago she started pooing in the house. I have taken her out walked her and she has done her business, but then when she comes in will mess. To top it all in the last couple days she has started to deliberatly urinate after comming in.
How can I get her out of this?

There has been no change in routine, she even watches me clean it up.........wagging her tail!!!!
