How much pressure does a collar really put on a neck: what a mannequin study found
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
"A collar is harmless as long as you don't pull on it" is the most common assumption, for dogs and ferrets alike. A UK study set out to quantify exactly what happens when you do pull, by fitting sensors to a reproducible neck model (study on doi.org). All our accessory guides sit under ferret accessories.

An instrumented neck, three standardized forces
Carter, McNally and Roshier, published in 2020 in Veterinary Record, tested seven different collars plus a slip lead on a plastic cylinder simulating a neck, fitted with a pressure sensor beneath the collar. Three forces were applied to the lead to reproduce real situations: a firm pull (40 N), a strong pull (70 N) and a jerk (mean 141 N, comparable to a dog lunging suddenly).
A tenfold gap between models
The pressure measured on the neck model ranged from 83 to 832 kPa depending on the collar tested and the force applied — a tenfold gap between the gentlest and the harshest model. Both collar type and force intensity had a statistically significant effect, but none of the seven models tested dropped, during a jerk, to a level the authors consider clearly free of injury risk.
What the study can't tell you
This protocol reproduces a generic canine neck, not ferret anatomy, whose thin and highly mobile neck has never been measured this way; no validated pressure threshold exists specifically for the species. The underlying principle it illustrates — the harsher the force, the higher the local pressure, whatever the collar — remains transposable as a matter of caution.
What this means in practice
For a ferret, whose cervical skeleton is especially fragile, this data reinforces the already documented case for a harness over a collar for any outing on a lead: a harness spreads force across the chest instead of concentrating it on the neck, exactly the area where this study measures the highest pressures during a jerk.

Frequently asked questions
Is a thin, soft collar automatically safer than a wide one?
No: in this study, width alone didn't predict the measured pressure — the collar's overall design mattered more, one more argument for a harness whenever a lead is used.
Does this study also cover ID collars worn without a lead?
No, the protocol only measures pressure from a lead pull; an ID collar worn without a lead carries a different, already documented risk tied to snagging on an object.
