Jabba at 18 weeks is fully house trained and goes out in the back yard. Training a puppy to do stairs is a chore however, stairs with just treads and no backing, like you have on the steps to a deck usually make it almost impossible. With a little kibble and patients he now booms up and down with no problem. Upside is, the stairs (carpeted) to the bedrooms seem too daunting. Gotta love the goofy little guys!
