ULTRA-PLUS Prong Collar - Center-Plate, Assembly Chain & 2 Rings, Stainless Steel 3.0 mm (Short)

ULTRA-PLUS Prong Training Collar - Center-Plate, Assembly Chain, 2 Rings, Stainless Steel (3.0 mm Short)

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 this 3.0 mm 'Short Version' delivers the strength of a 3 mm wire gauge in the compact footprint of a 2.25 mm collar - in durable stainless steel.

The 3.0 mm Short advantage

The prongs are the same physical size as our 2.25 mm gauge but carry the strength of a 3 mm gauge - a discreet look with serious holding power, suitable for dogs up to 88 lb (40 kg).

Frequently asked questions

What makes the 3.0 mm Short Version special?
It keeps the compact, discreet footprint of a 2.25 mm collar but carries the holding strength of a 3 mm wire gauge - a low-profile look with serious control, suitable for dogs up to 88 lb (40 kg).

What are the two rings for?
The live ring engages the martingale tightening for an active correction, while the fixed (dead) ring gives a static, non-tightening attachment - clip to the live ring for training corrections, or to the fixed ring when you want a steady, non-closing fit.

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.

Should I use a backup connection?
Many handlers clip a short backup link from the prong to a flat collar or harness, so that if a link or buckle ever opens under a hard hit the dog stays connected - inexpensive insurance against an escape.
