Threshold
What Is Threshold?
Threshold is the point where a dog begins moving from being able to process what’s happening around them toward becoming too overwhelmed, excited, fearful, frustrated, or aroused to respond as they normally would.
Understanding threshold is especially important when working with reactive dogs.
Under Threshold
When a dog is under threshold, they can still think and process information.
They may notice the trigger, but they’re still capable of responding to you, taking food, following cues, and making choices.
This is generally where productive learning can happen.
Approaching Threshold
Dogs often give us signs before they completely lose the ability to respond.
You might notice staring, body stiffness, changes in breathing, leaning forward, closing the mouth, raised posture, whining, or increasing difficulty responding to familiar cues.
Recognizing these earlier signals gives us an opportunity to make an adjustment before the dog goes over threshold.
Over Threshold
Once a dog goes over threshold, thinking and responding can become significantly more difficult.
This may be when we see barking, lunging, pulling, frantic movement, or other intense reactions.
At that point, trying to teach something new is usually much more difficult.
Creating distance and helping the dog recover may become the immediate priority.
Distance Can Change Threshold
A dog may be perfectly capable of watching another dog from fifty feet away but struggle dramatically at fifteen feet.
That distance can become part of our training strategy.
We begin where the dog can still think and learn, then gradually change the distance as their ability improves.
Trigger Stacking Can Change Threshold Too
Threshold isn’t necessarily the same every day.
Several exciting, stressful, or frustrating events can accumulate.
A dog who normally handles something well may react much more strongly after several other challenging experiences have already occurred.
This is one reason understanding trigger stacking can be so important.
Threshold Can Also Describe Physical Boundaries
In dog training, the word threshold can also refer literally to boundaries such as doorways, gates, crate openings, or entrances.
Teaching a dog to wait calmly at those physical thresholds can be an important impulse-control and safety exercise.
The Bigger Picture
The goal isn’t simply to stop a dog once they’ve gone over threshold.
Whenever possible, we want to recognize what’s happening earlier and work where the dog is still capable of learning.
The better we become at recognizing the approach to threshold, the more opportunities we have to help the dog before the reaction takes over.
