Herm Sprenger Curogan Prong Training Collar, Black 16in x 2.25mm with Quick-Release Buckle

Herm Sprenger’s Curogan prong training collar is designed to support leash communication and training, with a ClickLock quick-release buckle and nickel-free Curogan alloy.

• Fits necks up to 13–14 in (33.02–35.56 cm) — choose by neck size rather than the collar’s overall length.
• U.S.-made Biothane insert — adds stability to the buckle connection and a color-accent option.
• Assembly chain loop tightens when a dog pulls on the leash — provides additional help during training.
• Made in Germany and assembled with its Biothane enhancement in the USA — combines German-made collar construction with a U.S.-made insert.
• Two O-rings — provide attachment points on the collar.

This collar is for handlers working on leash communication and behavior correction with a prong training collar. Its chain loop responds when the dog pulls, while the quick-release fastening makes it possible to put on and remove the collar without sliding it over the dog’s head. Correct sizing and placement matter: the collar is intended to sit snugly beneath the ears and along the jawline.

How does the collar support leash training?

The assembly chain loop tightens when the dog pulls on the leash, providing additional help with training and behavior correction. The collar is designed to communicate with the dog through this response; it does not guarantee a particular training result. For best results and safety, position it snugly under the ears and jawline.

• The collar is intended for training use.
• Keep its fit snug in the specified position beneath the ears and jawline.

Which size fits my dog’s neck?

This 16 in (40.64 cm) x 2.25 mm collar is intended for a neck size up to 13–14 in (33.02–35.56 cm). Use the indicated neck size when choosing; the 16-inch measurement is the overall collar length, not the neck-size limit.

• Adjust the collar by adding or removing pronged links to reach the desired length.
• Fit it snugly under the ears and jawline for safe positioning.

What are the buckle and collar made of?

The collar uses nickel-free, hypoallergenic Curogan, a special copper alloy, with a ClickLock buckle for fastening and release. The buckle lets you put the collar on or take it off without pulling it over the dog’s head. Its U.S.-made Biothane insert reinforces the connection between the buckle and prongs.

• A plastic black jacket slides on and off the unfastened buckle.
• The jacket does not interfere with the buckle’s function.
• The prong collar is made in Germany and assembled with its Biothane enhancement in the USA.

This collar suits handlers seeking an adjustable prong training collar with a quick-release fastening and a defined neck-size range. It is intended to sit snugly beneath the dog’s ears and jawline, with link adjustments available to achieve the desired fit.
