Herm Sprenger Curogan Prong Collar with O Ring

The Herm Sprenger Curogan Prong Collar is a trusted name in obedience training. Made in Germany from a copper-tin alloy that is nickel-free and rust-resistant, it’s ideal for dogs with light-colored coats or nickel sensitivity. It distributes even pressure around the neck without putting direct force on the trachea, allowing you to train with minimal tugging or correction.

A center plate ensures symmetrical tightening for balanced feedback, and the collar’s size can be adjusted by adding or removing individual links. Equipped with interlocking blunt prongs and a reliable assembly chain, this is a classic, safe alternative to choke chains and flat collars.

Care Instructions

Wipe down the collar with a clean, damp cloth after use. For stubborn dirt, use mild soap, warm water, and a soft-bristled brush, then dry thoroughly before storing. Curogan may naturally develop a darker patina over time. This is a normal cosmetic change and does not affect the collar’s performance. To restore shine, use Herm Sprenger’s Diamond Paste or a copper-safe metal polish.
