A great explanation of a shut down horse and what learned helplessness can look like.
I’d highly encourage everyone to have a read of this post!
A shutdown horse is a dangerous horse.
What is “shutdown?”
Shutdown refers to a dissociative freeze state where horses have been overwhelmed in training situations where they have felt trapped and unable to flee from what frightens them.
When they are unable to effect change on their environment and free themselves from the overwhelming fear and stress, their nervous system responds by trying to protect them by dissociating.
This shut down state is also known as learned helplessness.
A common example of this is seen when people attempt to desensitize horses to things they’re afraid of but instead use “flooding” aka overwhelming the horse with stressful stimuli while blocking their ability to escape.
Oftentimes, this method is sustained until the horse freezes and stops outwardly reacting, effectively entering a learned helpless state.
This frozen state is then mistake for “not being afraid” when really the horse is just resorting to a different nervous system response: freeze.
Horses in this state can often appear lethargic, sleepy and “relaxed.”
Their lack of response to their outward environment is mistaken for them being okay with what is happening.
But, this is where the danger comes in.
They can “wake up” from this state if stressors stack enough or there’s a big enough trigger.
Then, when they do, they often respond explosively and seemingly “out of nowhere.”
Their response is disproportionate to the final stressor that triggered it because it’s the explosion of internalized dormant stress that they are finally letting out.
It’s like a “rebound effect” where they respond in explosives as a means of trying to alleviate chronic stress.
The reason why this happens seemingly out of nowhere is because they’ve been previously conditioned to internalize stress and hide the outward signs of it because the freeze response is what is reinforced by trainers.
So, they learn to shutdown and freeze in lieu of showing outward signs which makes them obedient to an extent but it’s also like taking the batteries out of a smoke alarm.
When there IS a fire, you get no warning until it’s already completely ablaze.
Well intentioned people then buy these horses and are surprised by sudden explosives and a horse who seems nothing like the one they bought.
This is why it’s important to train for a relaxed nervous system while performing desired behaviors NOT just train for obedience without factoring in the level of stress a horse is under.
Obedience means nothing if it happens under duress and results in a highly unpredictable horse.
Horses who communicate their stress offer the opportunity for their caretakers to see it and help to alleviate it. This then reinforces trust and safety.
Horses who hide and mask their stress until they can’t anymore are explosive and often surprise their human caretakers with their reactions, putting EVERYONE more at risk.
If you’re interested in learning more about shutdown in horses, I’m currently working through a series of case studies on my community page, one of whom is a shutdown horse.
