I'm going to brag. When I'm at work and Gauge can't hold it anymore, he jumps in the bathtub and poops. I wish I could take the credit but I can't. My son used to play travel soccer and Gauge got sick(diarrhea) during one tournament and our hotel had a walk-in shower, so he used the bathroom in the shower. Now whether or not, my good boys registered with him or not, ever since, when he can't hold it, he jumps in the bathtub and does his business. I think that's mad smart and it makes accidents easy to clean although they are rare, about 2 or 3 times a year. But another reason why Gauge is the smartest and best dog ever, imo.
