ULTRA-PLUS Prong Training Collar - Center-Plate, Assembly Chain, Chrome-Plated Steel

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, finished in bright, polished chrome-plated steel.

Why handlers choose it

Frequently asked questions

What size dog is the 2.25 mm gauge for?
The 2.25 mm gauge suits small-to-medium dogs; larger, stronger dogs are better matched to a thicker gauge such as our 3.25 mm or 3.99 mm options.

How does chrome-plated compare to stainless or Curogan?
Chrome-plated steel has a bright, polished look at a lower price, but the plating can wear over time with heavy daily use; for the longest service, and for nickel-sensitive dogs, solid stainless or nickel-free Curogan hold up better.

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 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.

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.

Can my dog wear it all day or on a tie-out?
No - a prong collar is a training tool for active, supervised sessions and should come off afterward. Never use it for tie-out or unsupervised wear; use a flat collar or harness for everyday and downtime.
