We use an airtag for Bailey. Unfortunately she needs to be near an iPhone to be detected and if she manages to slide out of her collar (she did once) it's no use.
One thing from the Hound Hunters that resonated with my experience with Bailey little escapades was not to run after the escapee nor call her name (well, two things then). Last week she chased a runner so hard that she bumped on my front wheel and caused me to crash and got away from me leash dangling behind her. I was also carrying two poo bags at the time. After calling her a couple of times, which only caused her to start playing hide and seek, I decided to ignore her, picked up my bike and poo bags and proceeded toward the trash can without paying her any attention. Within a hundred feet she was right behind me asking 'what did I do wrong?' , I just calmly picked up the leash and kept walking her like nothing happened.
