Redirected reaction

How it works

It happens when a dog is past the point of processing and the arousal has nowhere to go. The nearest available target takes it: the leash, a housemate dog, or a hand reaching for the collar. It is not aimed at the recipient and carries no intent toward them, which matters both for how the dog is judged afterwards and for how the situation is handled. It is the main reason handlers are advised not to reach for a collar during a reaction.

What it looks like

Two household dogs are barking at something through a window. One turns and snaps at the other, who had nothing to do with it. Seconds later they lie down together as normal.

Commonly confused with

Over-arousal

Over-arousal is the state that makes this possible. A redirected reaction is one specific thing that can happen while a dog is in it, and it is about where the response lands rather than how high the arousal is.
