Built to the spec handlers already carry, and rated for the load.
Long lines, rough ground, and weather that ruins lesser webbing.
The same gear, for the dog who simply pulls like they are on shift.

Asked. Answered.
What is a martingale collar for?
It closes to a point you set and no further, so a dog cannot back out of it — but it never becomes a choke. It is the usual answer for narrow-headed breeds and nervous walkers.
How do I set the stop point?
Fit it over the head, then adjust so that when the loop is fully closed you can still slide two fingers under the collar. That is the limit it will ever reach.
Can they wear it all day?
Use it for walks and training. Like any limited-slip collar it is not an unsupervised, all-day collar.
How do I clean it?
Hand wash cool with mild soap and air dry.
