Dogs are fascinated by the bathroom. I knew that. All 7 dogs try to accompany me to the bathroom (very crowded) and watch me with puzzled expressions, as if to say, "Why don't you just pee on the floor like we do?" But I didn't realize until this week that the bathroom is a playroom even if no human is sitting on the toilet.
Rule #39 of Living With Puppies: ALWAYS SHUT THE BATHROOM DOOR
That's Berry in the picture, caught in the act. All the dogs were involved in this incident, but the rest of them scattered when I entered the room. Berry doesn't care if he gets caught. He'll look up at me and smile, and he knows that makes me laugh.
