What are Martingale Collars?

They are the safest and most commonly used collar for all sight-hounds as well as many other breeds.  Technically called a "double-loop" safety collar, it is also commonly known as a "Martingale" or "humane safety choke" collar.

Quite simply, it is two loops.  The outer loop being adjustable to the size of the dog's neck. The smaller loop is often referred to as the "the handle" and has a D-ring sewn onto it. When a leash is attached to the D-ring, the outer loop tightens around the dog's neck and prevents the dog from sliding backward out of the collar. The small loop allows the whole collar to decrease in size, evenly distributing pressure, and easing the strain on your dog’s neck and coat. The restraint is firm and secure, but never pinches or gags your dog.

Pacific Rain^TM Martingale Collars come in the following widths:   3/4 inch, 1 inch, 1-1/2 inch, and 2 inch.
