It is connected in the front, just under their jaw (that is why the collar has a strap around the muzzle)
So when they pull they are automatically turned around without tugging or pulling. They automatically stop/slow down once they start to feel the pull, so end up going nicely, not hanging full force on the end of the leash =P
I can hold their leash with my pinky now O_o
Best part is it doesn’t hurt them in any way! No pain, no stress or tension on their body! And since it snaps them out of it faster when getting over exited to see other dogs it actually helps them keep calm too!
The second strap going down to their collar is just a safety strap in case they wiggle out
They never get any tension on their neck.
