Herman Sprenger ULTRA-PLUS prong collar - stainless steel - 58 cm / 3.2 mm

The classic Herman Sprenger ULTRA-PLUS prong collar in the 58 cm length, for larger dogs with a broader neck. This is the silver version - without the black galvanic coating, so the steel colour stays stable for the whole life of the collar.

Construction

Made of stainless steel - resistant to corrosion and moisture, smoothly polished. The prongs sit evenly around the dog's whole neck, so with correct use they give a precise cue without excessive pressure in any single spot. A 3.2 mm wire and 4 cm links are the standard size for medium and larger dogs.

The ULTRA-PLUS system

ULTRA-PLUS is a length-adjustment system based on an even number of links - you add or remove links in pairs, and each change shifts the circumference by 8 cm. That way the collar fits precisely to a particular dog's neck.

ClickLock buckle

ClickLock is Sprenger's patented buckle. It closes in one move, holds firmly under load and won't release by accident. The leash clips into the fixed ring by the buckle.

For on-leash work only

This prong collar is intended for on-leash work during active training. It should not be used during free running, transport or while the dog is unsupervised.

Not sure this size is right?

A prong collar should sit snugly just below the dog's jaw, without sagging - that's how we size it. How to measure the neck, and what to do when the measurement falls between sizes, is covered step by step in our prong collar sizing guide.
