Herm. Sprenger Ultra-Plus Prong Dog Training Collar, Anti Pull Training Pinch Collar, CUROGAN (3.0 mm x 17″ Neck Size; 20″ Chain Length) – O-Ring Version

About this item Improved Design: Designed for precise correction and pull limitation, this unique collar features prongs of the same size as our 2.25mm wire gauge but with the enhanced strength of a 3mm gauge, ensuring effective training with increased durability. Durable Material: Curogan is rust-resistant but may darken over time due to its high copper content. This change is easily corrected with metal polish, bringing back its original luster. Adjustable Fit: The initial length of this collar fits dogs with neck sizes up to 18 inches. For larger neck sizes, additional middle links are required. Please note that due to the new unique design, standard middle links are not compatible and specific links designed for this model must be used for adjustments. Recommended by Professionals: This collar is engineered to distribute pressure evenly for safe behavioral correction without choking, earning the trust of dog trainers and veterinarians for its humane effectiveness in training. German Craftsmanship: Proudly crafted in Germany, ensuring the highest quality and durability in every collar manufactured by Herm Sprenger.
