My puppy Zayn is a 9 month old Cairn Terrier/Shepherd mix and has been potty trained to poop outside since he was 3 months old. The problem is, I live in a lively apartment complex and there always seems to be some distraction when we go outside...kids playing, other dogs, blowing leaves!! Zayn is so easily distracted by them, that he'll forget he has to go. He sits by the door, will bark softly to get my attention, but once i leash him and go outside, he's in play mode! He wasn't always like this, how do I stop this!??? It's such a pain especially when I need to head out to work and he won't go...knowing he very well has to poop and will be crated for the afternoon!
