Yes, my Shiz Tzu is 8 years old and pees in the house, only at night when I'm sleeping. I can't catch him in the act, so what am I to do, Stay up all night and take him to the bathroom? Also when I'm with him all day he goes to the door, it's only when I'm in bed he gets out of the bedroom and then he lifts his leg and pees on anything he can. So does anyone have ideas? I'm not gonna tie him up at night but I can leave him in the garage, but, he has to stay in the garage all day while I'm at work, I hate to leave him in the there at night too! Any ideas. He is so cute, but he has control over me, not me "over" him.
