Threshold

Reactivity and fear

The point at which a dog stops being able to think clearly about what is happening around them.

How it works

Below it, a dog can notice something, take food and respond to a cue. Above it, cues, food and consequences all stop landing, because the dog is no longer processing what follows what. This is a statement about state and timing rather than about willingness. It also sits in a different place for every dog, and in a different place for the same dog on different days, since the previous few hours change where the line falls.

What it looks like

A dog can watch another dog at a hundred and thirty feet, take a treat and look back at their handler. At sixty feet they stop eating, and the same treat is refused. Somewhere between those two distances is where this dog's line currently sits.

Commonly confused with

Trigger stacking
Threshold is the line itself. Trigger stacking describes how that line moves closer across a day as stressful events accumulate, which is why a dog can manage something on Tuesday and not on Thursday.
