The Grot collar (or "French collar") is a lightweight paracord slip collar that sits high on the neck, just behind the ears — the ideal position for clear, low-effort communication and control. Two adjustable stoppers hold it exactly where you want it, so it slips on in a second and stays put without choking.
Strong 4mm USA-imported 900 paracord — thin, light and low-profile
Two stoppers for a secure, adjustable fit
Sewn and heat-sealed for durability
Stainless steel O-rings (~300kg tensile strength)
Suitable for all breeds — a genuinely useful everyday training collar
Choosing a size — the measurement is the total collar length; pick by your dog's size and the stoppers fine-tune the fit:
45cm – Small: Whippets, French Bulldogs, mini breeds and small terriers
65cm – Large: Labradors, German Shepherds, Boxers, Pointers
75cm – X-Large: Rottweilers, Dobermanns, Mastiffs and broad-necked bull breeds
As a general rule, you should be able to fit two fingers between the collar and your dog's neck — if you can't, it's too tight.
Please note: as with any training tool, you must condition your dog to it for the best results — equipment doesn't magically fix issues, but introduced and conditioned properly it builds clear communication between you and your dog. We strongly recommend seeking professional advice before using any training tool; browse our list of dog trainers and behaviourists here.

I ordered two of these the first one I used was completely useless as the stoppers wouldn’t hold in place luckily the spare one I ordered seems to be better and doing its job

Feel far more free in terms of what spare collar I use when using the prong collar

Instant result!
Great collar, immediate change in behaviour!
I never in my wildest dreams imagined that - after trialing with a flat collar, a halti collar, choke collar - this would be so effective so quickly.
My dog was a high energy walker, sniffing in all directions, erratic and unpredictable leaps and pulling. With the prong collar, he is a different dog.
Plus, being sensitive, I thought he would be anxious about it. But no, he actually enjoys walks with it than he ever did before!
Thanks!
