If you're looking to level up your schooling sessions, adding some horse jump fillers is a total game-changer. Most of us start out with just a few poles and a couple of blocks, but eventually, you realize that your horse is getting a bit too comfortable. They might be clears-machines over plain cedar rails, but the second you head to a show and see a bright yellow gate or a box of plastic flowers, everything falls apart. That's where fillers come in—they bridge the gap between "home-safe" and "show-ready."
Why Fillers Actually Matter
It's easy to think that a jump is just a jump, but horses definitely don't see it that way. Their vision is geared toward spotting predators and changes in the environment, so when you stick something solid or brightly colored under a rail, it changes the entire "profile" of the obstacle. A horse that happily steps over a pole might suddenly decide that a striped plank is a horse-eating monster.
Using horse jump fillers helps build a horse's confidence and teaches them to focus on the rider's aids rather than the "scary" thing underneath them. It's about desensitization. If they've seen it all at home—from flower boxes to lattice gates—they're much less likely to have a meltdown when they walk into a busy competition ring for the first time. Plus, let's be honest, a plain arena looks a bit boring. Adding some color makes the whole riding experience feel a lot more professional and fun.
Common Types of Fillers You'll See
There isn't just one type of filler; they come in all shapes, sizes, and levels of "spookiness." Depending on what you're training for, you might want to mix and match.
Flower Boxes and Brush
These are probably the most classic horse jump fillers out there. They're usually long, rectangular boxes filled with plastic flowers or greenery. The great thing about these is that they aren't very intimidating for most horses because they have a "soft" look. However, they do fill the space under the rail, which makes the jump look more solid. If you're just starting out, some simple green brush or white flowers are a great way to introduce the concept.
Gates and Planks
Now we're getting into the stuff that really tests a horse's focus. Gates can be hanging (hooked onto the cups) or standing (sitting on the ground). Because they often have vertical or horizontal slats, they create a lot of visual "noise." Planks are similar but usually solid and wide. These are notorious for causing "looky" behavior because they create a solid wall effect. If your horse tends to be a bit peeky at the base of the fence, practicing with these is essential.
Walls and Pickets
A full wall is the ultimate test of bravery. While most schooling fillers are just "mini walls" (blocks that stack up), they serve the same purpose. They block the horse's view of what's on the other side, which requires a lot of trust. Picket fence fillers are also popular; they look cute, but those pointy tops can sometimes make a horse back off if they aren't used to them.
DIY vs. Buying Professional Gear
Let's talk about the elephant in the room: professional jump equipment can be expensive. If you have the budget, buying high-quality PVC or treated wood fillers is definitely the way to go. They last forever, they're weather-resistant, and they usually come in standard show dimensions.
But if you're on a budget, you can get pretty creative with DIY horse jump fillers. I've seen people use all sorts of things. Old tires (painted in bright colors), plastic barrels, or even those heavy-duty storage bins can work wonders. Just make sure whatever you use is safe. You don't want anything with sharp edges or something that a horse could get a leg caught in if they have a clumsy moment.
If you're handy with a saw, you can whip up some simple plywood "V-fillers" or "A-frame" boxes in an afternoon. A bit of outdoor paint and some stencils, and you've got something that looks almost as good as the pricey stuff. Just remember to weight them down if you live in a windy area—nothing ruins a schooling session like a flying piece of plywood hitting your horse's legs.
Training Tips for Spooky Horses
If your horse thinks the world is ending every time you introduce a new filler, don't sweat it. It's totally normal. The trick is to not make a big deal out of it. If you approach the jump all tense and staring at the filler yourself, your horse is going to think, "Yep, Mom's worried, I should definitely be worried too."
Start by placing the horse jump fillers off to the side of the arena. Let them sniff it, walk past it, and realize it doesn't move. Then, move it under a jump, but keep the rails low. You want to set them up for success. If they stop, don't get mad. Just circle back, keep a leg on, and encourage them over. Sometimes, placing the filler behind the jump (on the landing side) first can help them get used to the colors without feeling like they have to clear it.
Another pro tip: use ground poles. Put a pole a few feet in front of the jump to help the horse find their take-off spot. When they're focused on where to put their feet, they spend less time staring at the scary blue stripes on the gate.
Keeping Things Fresh and Interesting
One mistake people make is setting up their arena and leaving it that way for six months. Horses are smart—they'll get used to those specific horse jump fillers and stop paying attention. Every few weeks, try to swap things around. Move the red gate to the oxer, put the flowers under the vertical, or flip your planks upside down.
You can even play with the "negative space." Instead of putting the filler right in the middle, slide it to one side. This teaches the horse to stay straight and not drift away from the "scary" part of the jump. The goal is to make them adjustable and brave, no matter what's sitting on the ground.
Safety and Maintenance
No matter how cool your fillers look, safety has to come first. Check your equipment regularly for cracks, splinters, or peeling paint. If you're using plastic fillers, make sure they aren't becoming brittle in the sun, as they can shatter if a horse hits them hard.
If you use wooden fillers, a fresh coat of paint every season isn't just about aesthetics; it helps protect the wood from rot. And always, always make sure the filler isn't taller than the actual jump cups. If a horse hits the rail and it can't fall because the filler is in the way, you're looking at a dangerous situation. There should always be a bit of "daylight" between the top of the filler and the rail.
Final Thoughts
At the end of the day, horse jump fillers are there to make you a better rider and your horse a more confident athlete. They add variety to your training and help prepare you for the unpredictability of the show ring. Whether you're building your own from scratch or investing in a set of professional gates, the effort you put into schooling over different visuals will pay off ten-fold when you finally hear that starting bell. So, go ahead—get creative, get some paint, and start building a more interesting course for you and your horse.
