Well this sounds familiar to me. My Husky...now almost 7 years old has peed on my bed. The first time it happened, I think it was because he was sleeping really hard because it was just a big puddle (old bed). Happened again about a year ago in a rental house we'd been in for a year (new bed, sterns and foster as well). Recently he peed on our bed about 6 months after moving into our new house. It's brand new so no dog has peed in there. But he peed on there, then I washed the comforter and he peed on it again...this time I could see the trail so he was standing when he did it. We usually let him rome but now we shut he door. At night he sleeps at the foot of the bed. The best part is that I woke up one morning and noticed he had got on top of my love seat. I don't know why, it's never happened before. He must have done it in the middle of the night. Anyway now he's shut in the bedroom with us at night. I have no idea what is going on with him. He was given a clean bill of health at his checkup but no urinalysis has been done yet. Have you figured yours out yet? Anyone know why this would be going on?
