Potty time

Tonight I got Brycen out of the bath tub and told him to run in and pick out his Pj's from his bedroom. I didn't hear anything coming from the room, and we all know that that's bad news, so I look in and he is peeing on the floor right in the middle of the carpet. trying to stay as calm as possible I ask him what in the world he was doing, and he gave me the most Innocent look and said I had to go potty. I asked why he decided to do it right in the middle of the floor???? He said well that's what the dog does!
