My wife and I adopted a 3-4 yr old shephard/hound mix from the local humane society about 6 months ago. She was a 'special needs' dog, with a lot of shyness problems. We worked with her for a quite some time and seemed to gotten her house-trained. Recently, she started to pee in the house while we are at work. Ruling out medical and/or problems with holding pee, are there any reasons for this?
