Product Description
The Herm Sprenger Ultra-Plus Prong Collar is a professional-grade training tool designed for effective, humane, and consistent obedience training. Manufactured in Germany, this pinch collar features a specialized Curogan construction—a copper and tin alloy that is entirely nickel-free. This makes it an ideal choice for dogs with sensitive skin or nickel allergies, providing a safe alternative to standard steel collars that may cause irritation. The design utilizes a center-plate configuration that ensures even pressure distribution around the dog's neck rather than targeting the trachea. This symmetric pressure feedback provides clear communication during leash training, helping to reduce pulling, lunging, and reactive behavior without the need for harsh jerking or excessive tugging. The 3.2mm link thickness and 23-inch length offer a durable, robust solution for medium-sized dogs. Because Curogan has a high copper content, the links may naturally oxidize or darken over time; this is a characteristic of the high-quality alloy and does not compromise the structural integrity or performance of the collar. Whether you are working on basic leash manners or advanced obedience, this authentic German-engineered tool offers the precision and reliability expected by professional trainers worldwide.
