Correcting the dog There are many methods of correcting the dog. Typically these include choke collars, water squirt guns, electroshock, and sound. So we opted for choke collars. They are intended to pinch the fur or neck skin in such a way to immediately grab the dog's attention, but without causing actual harm. To do this, it is very important to use them correctly.
Incorrect use can hurt the dog.
And choke collars should never be left on an unattended dog. When you apply correction using the choke collar, you start out with slack in the leash. Snap the leash suddenly so that the collar slides tight. Some fur and skin from the back of the neck will catch in between the rings and chain and pinch the dog. This is very much like how a mother dog will correct a puppy - grabbing the skin at the back of the neck with her teeth.
