I have been taking my 5 month old Shorkie (Shih Tzu and Yorkie) out to do get him to do his business, but he just wants to play and sniff without doing his business. We stay out for at least 30 minutes and then I bring him back in and he urinates and defecates on his newspaper. How do I get him to just go outside and not come back in and do it on the paper? Should I remove the paper after he comes back in? I keep him in a big room with easy to clean floors while at work with newspaper on it. Should I crate him while at work? I do work some 10 hour days and some 5.5 hr days. Is 10 hours too long to crate him? I need help! Thanks!
