The Canny Colossus is a no-pull headcollar designed specifically for large and giant breed dogs with neck sizes of 58-69cm. Works behind the head rather than on the nose or muzzle for comfort and control. Suits Newfoundland, St Bernard, Pyrenean Mountain Dog, and other giant breeds. 278g robust construction. Available in black. £29.95. SKU COL001. By The Canny Company.
Why We Recommend It
A pulling giant breed dog is a different problem category from a pulling medium-sized dog. A Labrador pulling is unpleasant. A Newfoundland or St Bernard pulling is a genuine safety risk — for the handler, for other people, and for the dog. Standard headcollars don't fit giant breeds, and the ones that do often apply nose pressure that these powerful dogs simply ignore or resist. The Canny Colossus solves this with the same behind-the-head mechanism that makes the Canny Collar effective — but built to the scale and strength required for giant breeds.
Key Benefits
- Designed for giant breeds — 58-69cm neck; the size gap that standard collars don't cover
- Works behind the head — comfortable, effective, non-confrontational
- Robust 278g construction — built for the power of giant breed dogs
- Award-winning behind-the-head mechanism — same design as the Canny Collar
- Transforms walks with giant breeds — from dangerous to manageable
My friends, I am a Labrador. I am not a giant breed. But I have met Newfoundlands, and I want to tell you that they are very large indeed. A Newfoundland that pulls on the lead is a force of nature that requires a serious solution. The Canny Colossus is that solution. It works the same way as the Canny Collar — behind the head, comfortable, effective — but built for dogs that make me look small. I endorse it on behalf of all the handlers who have been pulled into hedges, puddles, and other dogs by their enormous, well-meaning, completely uncontrollable giant breed companions. 🐾

How To Use

Care Guide

- Air dry naturally — do not tumble dry or apply heat

- Inspect stitching and attachment ring regularly for wear
- Replace immediately if any component shows signs of damage
Professional Insight
The Canny Colossus addresses a genuine gap in the headcollar market. Giant breeds — dogs over approximately 45kg — generate pulling forces that exceed the design parameters of standard headcollars, and their neck circumferences often fall outside the sizing range of standard products. The behind-the-head mechanism is particularly important for giant breeds: nose-based headcollars on large, powerful dogs can cause cervical spine stress when the dog pulls hard against the nose pressure, as the rotational force applied to the head is multiplied by the dog's body weight. The behind-the-head mechanism avoids this by applying pressure at the occiput rather than rotating the head, which is both safer and more effective for dogs of this size.
Training Academy Tip 💡
Gundog Training Academy Tip
Giant breeds present a specific training challenge: pulling behaviour that would be manageable in a smaller dog becomes a genuine safety issue before the dog is even fully grown. The Canny Colossus is the management solution that makes walks safe while you work on the underlying behaviour.
A 70kg dog that walks calmly on a loose lead is a joy. A 70kg dog that pulls is a liability. The Colossus gives you the control to make walks safe and enjoyable while the training does its work.
Complete Your Setup
Pair with the Canny Training Lead for versatile control during walks and training sessions. The Canny Recall Lead provides safe distance work for giant breeds that are not yet reliable off-lead. Use Wildcrofts Farmhouse Feast (62% protein) as a high-value reward for calm walking behaviour — even giant breeds respond to the right motivation.

FAQs
Which breeds does it fit?
Dogs with neck sizes of 58-69cm — typically Newfoundlands, St Bernards, Pyrenean Mountain Dogs, Great Danes, and Irish Wolfhounds. Measure at the widest point before ordering.
How is it different from the Canny Collar?
Same behind-the-head mechanism, built to giant breed scale. The Canny Collar covers up to 58cm (Size 7); the Colossus covers 58-69cm.
Is it strong enough for a very large dog?
Yes — the 278g construction with heavier webbing, stitching, and hardware is designed for dogs that can pull a handler off their feet.
My giant breed resists headcollars — will this be different?
Very likely. The behind-the-head mechanism doesn't trigger the head-shaking and pawing that nose-based headcollars produce. Most dogs accept it within a few sessions with gradual introduction.
