Our black lab is about 13 years old. He still has alot of energy, eats well, gets up and down the stairs. We generally take him out for a walk 2 to 3 times daily. He is on a strict diet of dry dog food and almost never has any "people" food. The problem we are having is that it seems to be on a daily basis now, he looses his bowels between 3am and 4am on a daily basis. Its like clockwork. He is also starting to lose his control of his bladder, because he drips urine on the floor quite frequently. Does anyone have any experience with this issue in an older Lab?
