Yeah, our mutt is pretty easy. A friend of ours has to walk her retriever at least three times a day, the last time in the evening, no matter how late she gets home, - apparently potty break ain't happening except on a walk. The evening routine with ours is easier. Somewhere around 8:30 or so, we call her to the door, let her out, she goes into her enclosure and pees, and runs back in, and done. And I am thankful each and every time, especially at -30C. Hell, at that temperature it takes longer to get dressed up than it does to do a walk.
It took her two days to get the bell routine down pat. Now if I could just persuade her to come when called...
