A few weeks ago we gave our dog a bath after he had some diarrhea while going outside. In the days following his bath for some reason he started to pee and poop in the house. He is 10 years old and has been housebroken for years and has not pooped or peed indoors for years. We were not rough on him nor have we abused him or even yelled at him but for some reason he just wont stop peeing and pooping indoors. We let him outside often and take him for walks and we have also been praising him when he goes outside. We never catch him in the act of doing his business, it seems like it is happening right after we go to work in the morning. However this is not a new schedule or change of activity. It may also be happening when we are home but it is hard to tell exactly as we have not seen him doing it but it mostly seems to be taking place in the morning once we leave. We have ran out of ideas and do not understand why he is doing this so suddenly, its getting tiring cleaning up his mess!
