All Weather Nylon Martingale Dog Collar
The Martingale Collar-Slip Collar-Half Check Collar.
A martingale collar has 2 loops: the smaller loop is the “control loop” that tightens the larger loop when pulled to prevent dogs from slipping out of the collar.
Similar to a prong collar, the martingale has limited constriction on the dog’s neck and applies even pressure.
Martingale collars are recommended for small,medium and large breeds they can often slip out of standard collars.
They can, however, be used for any breed of dog.
Their no-slip feature has made them a safety standard at many kennels and animal shelters.
