ULTRA-PLUS Prong Training Collar - Center-Plate, Assembly Chain + Metal Quick-Release Buckle, Nickel-Plated

The ULTRA-PLUS is a professional prong-style training collar built for precise, controlled correction and pull limitation. Its center-plate links the prongs for a stable, evenly aligned fit, and the assembly chain is paired with a metal quick-release buckle made in-house by K9 Industries for fast, secure on/off - in bright nickel-plated steel.

Why handlers choose it

The metal quick-release buckle lets you put the collar on and take it off quickly without pulling it over the head, while the assembly chain provides martingale-style correction. Adjustable by adding or removing links.

Frequently asked questions

How is the metal quick-release buckle different from the ClicLock?
It gives the same quick on/off as the ClicLock but uses an all-metal quick-release buckle made in-house by K9 Industries, rather than the polymer ClicLock - a sturdier, all-steel option for handlers who prefer metal hardware.

How does the assembly chain limit pulling?
The assembly chain works martingale-style: when the dog pulls, the chain draws the collar to a controlled, limited tighten and no further, so the correction stays measured rather than continuous.

What size dog is the 3.25 mm gauge for?
The 3.25 mm gauge suits medium-to-large dogs; smaller dogs are better matched to our thinner 2.25 mm, and very large, powerful dogs to the 3.99 mm.

How does nickel-plated compare to stainless or Curogan?
Nickel-plated steel gives a bright, polished look at a lower price, but the plating can wear over time, and nickel can irritate nickel-sensitive dogs - if that is a concern, our nickel-free Curogan or solid stainless are better choices.

What does the center-plate do?
The center-plate links the prong sections at the front so the collar stays aligned and sits flat and stable around the neck, instead of bunching or rotating like a plain chain - giving more even, predictable pressure.

How should it fit and where does it sit?
An ULTRA-PLUS should sit high on the neck, just behind the ears, snug enough that it can't slide down to the wider lower neck where it loses effect. Add or remove links for that fit, and introduce it under professional guidance.

How do I size it - by the listed length?
Treat the listed length as a maximum, not the fit. Dial it in by adding or removing prong links so it sits snug high on the neck - better to start a little long and remove links than to run out of room.

Is a prong collar humane, and are the tips sharp?
The prong tips are smooth and rounded, not pointed - they apply even, distributed pressure around the neck rather than poking. Fitted correctly and paired with proper training it is a clear communication tool, not a punishment device; introduce it under professional guidance.
