Overwriting the Junk Files
If you’ve ever worked with a horse who seems to carry their past around like a weight on their shoulders, you know what I’m talking about. The horse who flinches when you reach for their face. The horse who plants their feet at the trailer even though they’ve loaded a thousand times before. The horse who was doing great for weeks and then one day just comes unglued for no reason you can see.
It’s easy to look at those moments and think something is broken. That your horse is damaged. That there’s some deep wound you’ll never be able to reach.
But here’s what I want you to understand: your horse isn’t broken. Their hard drive is just full of junk files.
How Your Horse’s Brain Stores Information
I like to think of a horse’s mind like a computer filing system. Every experience your horse has gets filed away somewhere in their memory. Good experiences, bad experiences, confusing experiences, scary experiences. All of it gets stored.
Now, here’s where it gets interesting. When a horse has a bad experience, that experience doesn’t just get filed away in some quiet folder in the back of their brain. It gets flagged. It gets priority status. It moves to the top of the search results.
Why? Because your horse’s survival depends on remembering the dangerous stuff. If a horse steps on a wobbly bridge and it shifts under their feet, their brain says, “Flag that. Bridges are dangerous. Remember this next time.” If a horse gets their face yanked on when someone cinches them up too fast, their brain says, “Flag that. Cinching means pain. Brace for it.”
These are the junk files. They’re not junk because the experience didn’t happen or because your horse is making it up. They’re junk because they’re outdated information that no longer serves your horse. That bridge is solid now. That person isn’t yanking on their face anymore. But the file is still there, taking up space, and every time your horse encounters something similar, that old file gets pulled up first.
Your horse isn’t choosing to be difficult. They’re running old software.
Why Flooding Doesn’t Delete the Files
This is where a lot of well-meaning horse people go wrong. They think that if they just expose their horse to enough pressure, enough stimulus, enough repetition of the scary thing, the horse will eventually “get over it.”
That’s called flooding. And yes, it can look like it works. You can flag a horse and sack them out and wave tarps and bags around them until they just stand there like a statue. But if you look closely at that horse, you’ll notice something. They’re not relaxed. They’re shut down.
There’s a big difference between a horse who is calm and a horse who has given up. A calm horse has soft eyes, a low head, maybe a cocked hind foot. They’re breathing. They’re present. A horse who has given up is stiff. Their eyes might look glazed. They’re not moving because they’re afraid to move, not because they feel safe.
That horse hasn’t deleted the junk file. They’ve just learned to hide it. And those hidden files have a way of coming back at the worst possible moments. You’ll be riding along, everything seems fine, and then something triggers that old file and your horse explodes. Bucks, bolts, rears, spins. It comes out of nowhere because it was never actually gone. It was buried.
The flooding approach is like compressing a file on your computer without actually deleting it. It takes up less visible space, but the data is still there. And when something triggers a decompression, all that old information comes rushing back at full force.
We don’t want to compress the junk files. We want to overwrite them.
How Good Experiences Overwrite the Bad
Here’s the good news. Your horse’s brain is not a locked vault. Those files can be changed. They can be rewritten. And the way you rewrite them is through stacking good experiences on top of the old ones.
Every single time you have a positive interaction with your horse, you are writing a new file. Every time you ask for something and they give it to you and you release the pressure immediately, that’s a new file. Every time you back your horse up and they stand there on their haunches, relaxed, breathing, waiting for you, that’s a new file. Every time you send your horse through something that used to scare them and they come out the other side and you rub on them and breathe with them, that’s a new file.
And here’s the part that matters most: those new files don’t just sit alongside the old ones. They overwrite them.
Think about it this way. If your horse had ten bad experiences with the trailer, they’ve got ten files that say “trailer equals danger.” But if you spend the next few months doing methodical, patient, step-by-step work around that trailer, and you stack up twenty good experiences, now you’ve got twenty files that say “trailer equals safe.” The old files don’t disappear overnight, but they start losing priority. They get pushed further and further down in the search results until your horse’s first instinct when they see the trailer is, “Oh, that’s where good things happen,” instead of, “That’s where bad things happen.”
That’s the power of repetition done right. Not mindless repetition. Not flooding. Intentional, connected, methodical repetition where every single experience reinforces the same message: you are safe with me.
The Connection Piece Changes Everything
Now, here’s where this gets really different from the old way of doing things.
In the old way, desensitizing is about the object. It’s about the flag, the tarp, the trailer, the bridge, the scary thing in the corner of the arena. The focus is on getting your horse to tolerate the thing.
In the new way, the focus isn’t on the thing at all. The focus is on the connection between you and your horse.
When I’m desensitizing a horse, I’m not thinking, “Can you stand still while I wave this flag?” I’m thinking, “Can you connect with me while this flag happens to be here?” Those are two completely different questions, and they produce two completely different horses.
A horse who has been taught to tolerate the flag will stand still while you wave it. But the moment something changes, the moment that flag shows up in a new environment or at a different angle or attached to something they haven’t seen before, they’re right back to square one. Because they didn’t learn to trust you. They learned to endure the flag.
A horse who has been taught to connect with you during the flag work will look for you no matter what’s happening around them. Flag, tarp, bag, loud truck, barking dog, whatever. Their first instinct isn’t to react to the stimulus. Their first instinct is to find you. Because every good experience they’ve had has been filed under one category: “When I connect with my person, everything is okay.”
That’s the file you want at the top of the search results.
What This Looks Like in Practice
So how do you actually do this? How do you start overwriting those junk files with good ones?
It starts with the basics. And I mean that literally. It starts with backing up.
Start where your horse is comfortable. If your horse is reasonably okay with you rubbing them with a flag, start there. Don’t start with the thing that sends them over the edge. Start with what they can handle and build from there.
Focus on connection, not compliance. When you’re working through desensitizing, tip your horse’s nose toward you. Ask for their attention. The flag is secondary. The connection is primary. When they tip that nose in and their eye softens, that’s when you take the flag away. Not when they stop moving. When they connect.
Use motion to your advantage. Don’t just do your desensitizing while your horse is standing still. Send them around with the flag present. Lead them with the flag. Back them up with the flag. The flag just happens to be there while you’re having a conversation about backing up, moving the front end, sending, drawing in. The more you can make the scary thing incidental to the real work of connecting, the faster those new files get written.
Get your horse physically tired before you increase pressure. This is a big one. If you want to do some heavier desensitizing work, do your groundwork first. Get your horse moving. Send them around. Work on transitions. Get them a little huffy and puffy. Then, when you bring the flag or tarp in with more intensity, your horse has more incentive to stand still and rest. They start associating the desensitizing with the rest period. The flag comes out and instead of thinking, “Danger,” they think, “Good, I get to stand here and catch my breath.”
Be thorough, not comfortable. Here’s where a lot of people sell themselves short. They desensitize their horse just enough that the horse looks okay, and then they stop. They stay in the comfort zone. But those junk files are still lurking. You need to push past comfortable. Wave that flag bigger. Bring it behind your horse where they can’t see it. Make noise with it. Tap them with it. Not to scare them, but to find out where the holes are. Because every hole you find and work through is another junk file that gets overwritten.
Why Setbacks Are Part of the Process
Here’s something I need you to hear, because it’s going to happen and I don’t want you to be discouraged when it does.
You’re going to have days where your horse seems to regress. Where they act like they’ve never seen a flag in their life. Where they come out of the stall spooky and reactive and you think all your work was for nothing.
It wasn’t for nothing. What you’re seeing is your horse’s brain doing a stress test. When pressure goes up, when the environment changes, when something is off, your horse’s brain runs a search. And sometimes, on a bad day, those old junk files still come up first.
That’s okay. That’s normal. That’s part of the process.
What matters is what you do in that moment. Do you panic? Do you back off and decide today isn’t the day? Or do you take a deep breath, go back to your tools, back your horse up, move the front end, send them around, and start writing new files right there in the middle of the chaos?
Because those are the most valuable files of all. The ones your horse stores during moments of real pressure, real uncertainty, real fear, where you showed up and guided them through it. Those files carry more weight than a hundred calm-day sessions. Those are the files that say, “Even when everything felt wrong, my person was there. Even when I was scared, connecting with them made it better.”
Those files don’t just overwrite the junk. They replace it with something bulletproof.
Your Horse Is Always Updating Their Files
I want to leave you with this thought, because I think it’s the most important thing I can tell you about desensitizing, about training, about horsemanship in general.
Your horse is always filing. Always. Every interaction, every session, every time you catch them in the pasture, every time you lead them to the hitching post, every time you put a saddle on their back. They’re writing files.
The question isn’t whether your horse is learning from you. They are. Every single day.
The question is: what are they learning?
Are they learning that you’re consistent? That you show up the same way every time? That when things get hard, you get calmer, not louder? That you’ll never put them in a position to fail? That connecting with you is the safest place they can be?
Or are they learning that you’re unpredictable? That sometimes you have boundaries and sometimes you don’t? That when they get scared, you get scared too? That forward is the answer to everything? That the pressure never really goes away?
Every one of those lessons is a file. And over time, those files stack up into a story. The story your horse tells themselves about who you are and whether you can be trusted.
You get to write that story. One experience at a time. One session at a time. One deep breath at a time.
So the next time you’re out there with your horse and things aren’t going the way you planned, remember: you’re not failing. You’re filing. And every good experience you give that horse is one more file that says, “I’m safe here. I’m understood here. I belong here.”
That’s how you build an unbreakable bond. Not by forcing your horse to forget the bad stuff, but by giving them so many good experiences that the bad stuff just doesn’t come up anymore.
If you’re ready to start overwriting those old files and building real connection with your horse, I’ve put together a free training that walks you through exactly how to get started. It’s available for a limited time and focuses on the safety and confidence that come from doing this work the right way.
