Herman Sprenger ULTRA-PLUS prong collar - 1 ring - black stainless steel - 60 cm / 4 mm

The Herman Sprenger ULTRA-PLUS prong collar in its largest size and a black finish. A 4 mm wire and 5 cm links make it the version for big, strong dogs of up to 70 kg.

Herman Sprenger is a German manufacturer with over 150 years of tradition - their equipment is a standard in professional dog training worldwide.

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 10 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. It sits at the top of the collar, and the leash clips into the fixed ring by the buckle.

Black galvanic coating

The base of the collar is stainless steel - resistant to corrosion and moisture. The black finish is created by galvanic blackening of the surface followed by polishing. The manufacturer states plainly that the coating is not permanent - over time, at points of contact and friction, it naturally wears through, giving a patina effect.

Sprenger also notes that on dogs with very light or white coats, the hair may discolour where it touches the black collar.

Important - for use during training 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.
