Last summer (when I only had one dog) when we went on vacation my aunt would come down to let the dog out and everyday she would clean up dog poop in my sisters room. But that was the only time that he did that. I think because there is a sliding door on my back porch and we'd keep the door open and shade closed during the summer so they can go out whenever they want. But recently, there was this one time that my one dog peed right infront of me on a bag of something(I forget what) but that was the first and last time he did that.
