I’m a harness girl. My dogs have collars to attach ID to but leashes are attached to harnesses. It was explained to me that the reason collars are recommended high on the neck for training is because of the sensitive structures in this area. Collar pressure and “corrections” given with the collar in this position will be much more aversive (painful) as opposed to when the collar is lower on the neck.
I trained my first dog using collar high on the neck and leash “corrections” I still feel very bad about that.
