We have a 5year old 'westie' that we bought approximately 8 weeks ago from a breeder. She was previously used as a breeding bitch and has been in good health. Her house training hasnt been a problem until a couple of days ago when she started pooing in the house. We wonder if this may be linked to her coming into season last weekend. Does anyone have any experience of this or can anyone confirm that the change in behaviour and coming into season are linked???
