Hauling horses.
The trailer is the most dangerous place your horse regularly stands, and the part of horse ownership people learn by getting away with it. Here is the version that does not rely on luck.
A horse that will not load is not an inconvenience. It is a horse that cannot go to the vet.
Everything below assumes the horse gets on. If yours does not, that is the first problem to solve, and it is a training problem rather than a strength problem. A horse that loads calmly can get to a clinic at two in the morning, evacuate ahead of a fire, and go somewhere fun. One that does not is stuck wherever it is standing.
The trailer check nobody does often enough
The floor
This is the one that kills horses. Mats trap moisture and urine against wood or aluminum, and rot works from underneath where you cannot see it. A floor can look fine and be gone.
Pull the mats out at least once a year, wash the floor, let it dry completely, and look underneath as well as on top. Poke suspect boards with something sharp. Aluminum corrodes rather than rots, and it hides it just as well.
Tires, including the spare
Trailer tires usually die of age, not mileage. The sidewall carries a four digit date code, and a tire more than about five or six years old is suspect however much tread is left.
Check pressure cold, every trip. Underinflation is what causes blowouts, and a blowout with horses aboard is the emergency you least want. Carry a spare that is inflated, and something to change it with that actually fits the trailer.
Brakes, lights and the breakaway
Trailer brakes need to work, be adjusted, and be set correctly on the controller. Test them on the way out of the drive rather than at the first hill.
The breakaway battery is the forgotten one. It is what stops the trailer if it ever comes off the ball, and a dead battery makes it decorative. Check it charges.
Plug pinouts, wire colors and what to check when the lights misbehave.
The hitch
Coupler latched and pinned, safety chains crossed underneath the tongue so the tongue lands in them, breakaway cable attached to the vehicle and not to the chains, lights plugged in and tested.
Crossing the chains is not fussiness. It is the difference between a dropped tongue digging into asphalt and one caught in a cradle.
Weight and capacity are their own subject, and the arithmetic catches people out. There is a calculator for that.
Getting on, and standing quietly once there
A trailer asks a prey animal to walk into a small dark box with a loud floor, then stand still while the world moves. That it works at all is remarkable, and it works because the horse was taught, not because trailers are inviting.
The horse that loads well was taught to follow a feel and to think rather than react, long before a trailer was involved. Most loading problems are really leading problems that only become visible at the ramp.
What to avoid, because it is what most people reach for: two people and a lunge line behind the hindquarters, food used as a lure while the horse is already worried, and rushing because you are late. All three teach the horse that the trailer is where arguments happen.
If you are fighting it, that is the thing to fix, and it is fixable. It is one of the most common reasons people call Kat.
Practical loading notes
- Load the heaviest horse on the driver's side in a straight load. Roads crown toward the shoulder, so weight sits better on the left.
- Tie after the butt bar is up, untie before it comes down. Getting that order wrong is how horses come out backwards in a hurry.
- Tie short enough that the horse cannot get a leg over the rope, long enough that it can hold its head at a natural angle. A horse hauled with its head cranked up cannot clear its airway and is more likely to arrive with a respiratory problem.
- Use a quick release knot or a breakaway tie. Every time.
- Practice when you are not going anywhere. Load, stand, unload, put the horse away. A trailer that only ever appears before something stressful becomes the thing that predicts stress.
You are carrying something that shifts its own weight
Everything happens earlier
Brake sooner and more gently than feels necessary. A horse braces against deceleration and cannot see it coming, so hard braking is what throws horses off their feet.
Leave far more following distance than you would in the truck alone, and start slowing for lights the moment you see them change.
Corners are the hard part
Take corners and roundabouts wide and slow. Lateral force is what horses balance against worst, and it is the reason a rig can feel fine on the straight and terrible on a mountain road.
Accelerate out of the turn rather than through it.
Mountain grades
Going down, select a lower gear and let the engine hold the speed rather than riding the brakes. Brake fade on a long descent is a genuine hazard here, and there are plenty of long descents between the Flathead and anywhere else.
Going up, be prepared to be slow and let people past.
Wind
A horse trailer is a sail. Crosswinds on open ground, and the shove from a passing semi, both move you more than you expect. Both hands on the wheel, ease off, do not fight it with a sharp correction.
Heat and airflow
A stationary trailer in sun becomes an oven very quickly. Do not park a loaded trailer and go for lunch. Keep vents open, keep moving, and in real heat travel early or late rather than at midday.
Long hauls
Offer water at stops. Many horses will not drink away from home, which is a good argument for getting them used to it beforehand and for carrying water from your own trough.
On very long trips, plan a proper overnight rather than pushing through.
Paperwork, and one rule people forget
- Weed seed free forage is required on all Forest Service land in Region One and on all public land in Montana. If you are hauling to a trailhead, the hay in the trailer needs to be certified. See the trail map for where that applies.
- Brand inspection. Montana has livestock brand inspection requirements that can apply when horses change ownership or travel, and the details depend on where you are going and why. Check the current rule with the Montana Department of Livestock before you need it, rather than at a checkpoint.
- Crossing a state line generally means a health certificate, often within thirty days, and a negative Coggins test for equine infectious anemia. Requirements differ by destination state and change, so confirm with your vet in good time. A Coggins is not a same day job.
- Carry copies in the truck, not just on your phone. Signal is poor in a lot of this country.
Think about this before it happens, not during
A breakdown with horses aboard is a different problem from a breakdown. Get as far off the road as you can, put out triangles well back, and leave the horses in unless there is a fire. A horse loose on a highway is far more dangerous than a horse in a stationary trailer.
Know who you would call. Roadside services vary in whether they will touch a rig with livestock in it. Some equine specific plans exist and cover hauling to a vet. Worth finding out what yours actually covers before the day.
In an accident, tell dispatch there are live horses aboard. It changes who they send and what they bring, and first responders are rarely equipped for large animal rescue without being told.
What to carry
- Inflated spare, jack that fits the trailer, lug wrench, wheel chocks
- Reflective triangles and a torch with working batteries
- Spare halter and a long lead per horse, plus a spare tie
- A sharp knife somewhere you can reach fast
- Water, buckets, and hay you can actually feed
- Basic first aid for horses and for people
- Paperwork: health certificate, Coggins, proof of ownership
- Your vet's number and one along the route you are traveling
If loading is the problem, that is the work
Teaching a horse to load calmly, stand quietly, and get off without rushing is training rather than restraint, and it holds up when it matters.
