The safest and most commonly used collar for all Sighthounds is the "double-loop" safety collar, know in some parts of the USA as a "martingale" or "humane safety choke" collar. Quite simply, it is two loops, an outer loop & the smaller loop is often referred to as the "the handle" and has a D-ring on it. When a leash is attached to the D-ring, the outer loop tightens around the dog's neck and prevents the dog sliding backward out of the collar. The restraint is firm and secure, but never pinches or gags the dog. Martingale collars are not guaranteed against damage for dogs who are leash pullers.
