Herm Sprenger - Curogan Prong Training Collar w/ Center-Plate & Assembly Chain

The classic ULTRA-PLUS prong training collar in Curogan — Sprenger's nickel-free copper alloy, the go-to choice for dogs with metal sensitivities (and it won't discolor light coats).
Center plate keeps the prongs positioned away from the dog's sensitive throat area
Martingale-style assembly chain limits pull and distributes pressure evenly
Adjust the fit by adding or removing links; sits high on the neck, just behind the ears
Sizes: 2.25mm × 16" and 3.2mm × 23"
Made in Germany by Herm. Sprenger, metalworkers since 1872
