Hi everyone. I have a huge pitbull/mastiff mix dog we call Shadow. He was already a pretty big pup when I got him,, and he already had the habit of pooing wherever he was, which for me amounted to around the immediate vicinity of the house. I don't tolerate that, so I began training him in terms of "no poo" areas, poo time when he's chained, and where to poo. It's a big property, I have another dog, Lassy, the bushes is all theirs, just don't poo in the yard. That's our deal. I found Shadow to be very trainable. Remove the poo from an area a few times, and he'd get the message. Things were going very well. until a mother dog from next door and her wild pups (she had them in the bushes on another property) started to come over at nights. The dogs became friends, and to cut a long story short, they were nasty. They messed in the yard like crazy, and Shadow picked up the bad habit. Things have improved, as the other dog owner and myself we were able to catch at least three of the five pups, and the mother and those remaining are bit more cautious about coming over. But Shadow's bathroom habits were derailed. Frustrating! Worse so since I'm not there to retrain. My mom is often left with the task of cleaning up. Not good. Whew! Now for my question. Does anyone here have a few tips they can share that I could get my mom and sis to use to help get him get back on track? He's a big dog now, and knows when we're upset with him for messing where he shouldn't. That says to me that he knows it's wrong and it may still be possible to get him to stop all together. Bear in mind I'm not there. I only see him every few weeks when I go home, and never for long so my contact time is limited. Thanks :)
