SIZE: This Herm. Sprenger fur saver dog collar is made of rust resistant black stainless steel and is designed for dogs with the neck size from 18 to 21 inches. Overall collar length is 23 inches (58 cm), and wire gauge is 3 mm. Link size 1.6 inch (4.1 cm) long and 0.5 inch (1.3 cm) wide.

IMPORTANT: It is especially important to choose the correct size. Please consider your dog's neck and head circumference when selecting the collar - the collar slips over the dog's head.

FUNCTIONALITY AND DESIGN: Black stainless steel fur saver collar has long links and martingale assembly chain. It is suitable for dogs with short hair as well as long hair. The chain serves as a behavior correction collar. The collar tightens when the dog is pulling on a leash. The control loop on the collar should have enough room to pull into a symmetrical triangular shape when a leash is attached and pulled. When the leash is attached and pulled tight, the O-rings on each side of the control chain should never touch. There should always be two fingers width (about 2 inches) between the side O-rings.

PROFESSIONAL QUALITY: Made in Germany with precise German engineering, Sprenger offers reliability and quality by the world's foremost manufacturer of top-quality training collars. Each O-ring is stamped with the Sprenger seal of quality HS-Germany.
