My dog is a master at worming out of his harness and so he is never tied anywhere because I know damn well he wouldn’t stay tied.
I may be overly paranoid, though. The day we adopted him, we walked out of the Humane Society and he instantly slipped his collar and took off running. I spent the most terrifying 15 minutes of my life running through woods calling for the dog hoping he hadn’t run the other way to the road and been killed. Turned out he’d done a lap around the building and gone back to the front door.
