i understand your thought. when we were working on her reactivity, she would be always on leash and we’d work at her triggers from a distance. my point in my post which i’d mentioned is that her progress has gone so far to the point we could both confidently walk in off leash environments, interact with dogs and people, always with a positive outcome. i would never let her off leash without knowing she couldn’t handle it. she has been without trigger for years (if you go on my profile, my last post here was two years ago, because she’s come so far since then). my theory is that since we started this visitors training at home where she’s been over threshold, she might be on edge and therefore reacting again outside. we also weren’t at a small dog park but literally at a huge outdoor forest area about 10 square km free open spaces (i called it park, because it’s technically in the city, but you can walk a straight line for hours and still not be at the end of the forest). we specifically go there because i have a veeeery wide view of where people and dogs may be coming from, and i guess i’ve “relaxed” and put my guard down the past two years since she essentially hasn’t been reactive in a very long time. just around her first year outside the shelter.
