Herm. Sprenger Stainless Steel Dog Collar with ClicLock Buckle Herm. Sprenger training collar with ClicLock buckle is made in Germany by the world’s foremost manufacturer of top-quality dog collars. Herm. Sprenger stainless steel dog collar with ClicLock buckle on the side is a newly designed alternative to traditional prong training collars. Quickly unfasten the collar even with one hand by unlocking the buckle, conveniently placed close to the assembly chain that links to the leash. Unlike prong collars with the centrally located buckle, this design still has a center fastener plate and provides even distribution of the pressure by prongs on the dog’s neck. The prong collar is made of durable, rust resistant stainless steel. Polished finish of the stainless steel offers a distinctive and modern look. This collar offers strength and durability. Assembly Chain The Herm. Sprenger training dog collar features a martingale style assembly chain. The chain tightens the collar if the dog pulls on the leash while walking. Solid Center Plate Due to symmetrical attachment of the links with the center plate, the collar places even pressure around the neck, pressing the skin in a ring. Swivel D-Ring Swivel D-Ring connects with the leash and provides a full 360-degree rotation. This feature prevents tangling and allows complete mobility of the leash. ClicLock Buckle Comfort and security are offered by patented “ClicLock” buckle made of stainless steel. The buckle is used to fasten the collar around the dog’s neck without pulling it over the head. Plastic jacket protects the clasp against unintended opening and soiling. The jacket is designed to slide out completely from an open buckle. If the jacket was lost, the function of the buckle mechanism will not be affected. The buckle functions as intended as long as you hear a loud click at the time of the closing. Effective Training and Behavior Correction Tool The training collar should fit snugly on the dog’s neck just under the jaw line, although, the collar should not fit too tight. The protective black plastic jacket on the buckle is designed to slide on and off the unfastened buckle. It is strongly recommended to use a backup collar while training your dog with the prong collar. A properly fit training collar is safe to use and is a very effective training and behavior correction tool. Consider consulting with a professional trainer before use. Made in Germany Made in Germany with precise German engineering, reliability, and quality by the world's foremost manufacturer of training prong collars for dogs.
