Herm Sprenger Prong Collar: CUROGAN

CUROGAN Prong Collar - The Hypoallergenic Choice for Your Dog

Discover the Herm Sprenger Prong Collar: CUROGAN, specially engineered for dogs with sensitive skin, nickel allergies, or light-colored coats. CUROGAN is SPRENGER's proprietary copper-tin-alloy that combines the strength and durability of traditional metals with hypoallergenic properties. If your dog has experienced irritation, redness, or allergic reactions to standard metal collars, the CUROGAN prong collar offers a gentle, effective alternative without compromising training performance.

Nickel-Free CUROGAN Training Collars

Many dogs suffer from nickel allergies that cause skin irritation, hair loss, or discomfort around the neck area. The Herm Sprenger Prong Collar: CUROGAN is completely nickel-free, eliminating this common allergen while maintaining the precision and reliability SPRENGER is known for. CUROGAN is perfect for breeds with sensitive skin—including Golden Retrievers, Poodles, and Bichon Frises—allowing you to train effectively without worrying about adverse reactions.

Less Staining on Light-Colored Fur With CUROGAN

One of the standout benefits of CUROGAN is that is leads to less discolorations on light-colored fur. Unlike traditional metals that can leave dark stains on white, cream, or light-colored coats, th shiny rose-gold CUROGAN wears to warm, copper-toned finish without transferring color to your dog's fur. This makes the CUROGAN prong collar ideal for show dogs, breeds with pristine white coats like Samoyeds, West Highland Terriers, and Maltese, or any dog owner who wants to keep their pet looking immaculate during training. If you prefer the shiny look of the CUROGAN chains you can simply polish it using our Diamond Paste Metal Polish. Please note that discolorations can still occur with CUROGAN, but are less likely to happen than with stainless steel chain collars. We do not recommend using black stainless steel training collars for dogs with light-colored coats, if you prefer to avoid discolorations.

Wire Gauges: Choose the Right Size for Your Dog

The Herm Sprenger Prong Collar: CUROGAN is available in three wire gauges to accommodate different dog sizes and training requirements. Select 2.25 mm for small to medium dogs, 3.2 mm for medium to large breeds, and 4 mm for large, powerful dogs. Each gauge delivers the same hypoallergenic benefits while providing appropriate feedback for your dog's size and strength.

3 mm Short Version Prong Collar for for Active and Reactive Dogs

For highly active, reactive, or high-drive dogs—such as Malinois, German Shepherds, and working breeds—the 3 mm short version prong collar in CUROGAN offers superior communication. The shorter links create more frequent contact points, delivering quicker, more precise impulses that help reactive dogs focus and respond faster. This version is especially popular among professional trainers working in protection sports, police K9 units, and advanced obedience programs where split-second responsiveness matters.

Additional Links Available: Customize Your Fit

Achieve the perfect fit with additional links available in CUROGAN. As your dog grows, loses weight, or progresses in training, you can easily add or remove links to maintain optimal collar placement high on the neck, just behind the ears. This adjustability ensures consistent, effective communication throughout your dog's training journey.

CUROGAN Material Benefits: Why Choose This Alloy

CUROGAN offers multiple advantages beyond its hypoallergenic properties. The alloy is highly resistant to corrosion, making it ideal for dogs that swim, train in wet conditions, or live in humid climates. The warm, copper tone that appears after a while is visually appealing but can quickly polished back to it's shiny appearance.
