33 cm closed and 42 cm all open (SLIDER KNOT- NO TOGGLES, NO PAW BEADS)

The EM collar is only an addition to a regular dog collar. Do not attach a leash to it!

The SLIDER KNOT option is a great option for puppies or dogs which are easily distracted by dangling things like the toggles on our regular cord lock stopper version. It still gives you some room for adjustment. Just wrap the overlapping strand around the collar, so it’s out of the way.
