PLEASE NO CHOKE CHAINS!!!!!
They cause such damage to the dogs trachea and muscles around the neck that some countries in Europe have banned them. They should be banned everywhere.
The collar you are speaking of with the short section of chain is called a Martingale. It utilizes the sound of the choke chain without the damage to the neck - providing the part of the collar that cinches up on the neck is at least 3/4" wide and stiff.
We believe if you are training properly then you should only need a flat, wide, stiff collar which disperses the energy and does no harm.
Love Them & Lead Them,
