Trailer dilemma--Horse is getting hurt in my new dream trailer--what to do?

I have a persnickety mare. She loads and rides in a trailer like a champ–until she doesn’t. I’m about to give you quite a bit of backstory, but I think it is necessary if you’re to be able to advise.

Our first trailer was a 1979 Circle J–straight load with mangers and a center divider. She self-loaded, and would ride in that trailer for hours over the most horrible forest roads imaginable–craters and boulders the whole way–then get out and ride into the mountains for hours like the trailer ride had been nothing. She also willingly and happily rode in other people’s two horse straight loads.

Back in 2016 I came into a little money and was able to get a new two-horse slant with a dressing room with a swing out saddle rack. Much nicer for me, and maresy seemed fine with it, too. We continued heading down horrible forest roads to get into the mountains, then doing demanding rides, and she was all for it.

Then, one day, a couple of years after buying the slant, she decided the slant stall was too short for her and she started fighting the divider–literally putting all four hooves against the front wall to try to push her way out of the stall. She was scrambling and falling and thrashing.

All on her own, she started turning around in the trailer, after self-loading, so that she was facing backwards. I closed the divider with her facing backwards, so that her head and neck hung over the divider. This seemed to make her very happy. For a while.

Then she decided that she didn’t like this either. So I latched the divider open and gave her a fully open trailer, with nothing to lean on, and nothing holding her inside. She was happy as a clam riding backwards with no restraints. Liked looking out the back door, which was open at the very top. This was even working with her mini companion back there with her. They each assumed the same positions they had taken when the divider was in use–her facing backwards, and him facing sideways. Together they happily traveled down horrible forest service roads like this, and got out and hit the trail, none the worse for wear.

Problem was, the two horse slant was really a cheep trailer with leaf springs–no independent suspension–and it was getting rattled to pieces—stuff was falling off, the dressing room door was hard to unlock because the door was getting knocked out of plumb, the fenders were falling off… you get the idea. Plus my horse was getting arthritic by now and I felt the slant trailer wasn’t doing her any favors with all its jouncing. I wanted something with a smoother ride. And, I felt that riding loose in an open stock, as they were, was asking for trouble in an accident.

She’d always ridden great in a straight load, so I started looking for a quality used straight load–and I found one. A 2005 Hawk in like-new condition–warmblood size, breast and chest bars, removable divider, nice dressing/tack room. I had the ditch side stall customized for the mini–a lower breast bar, and a divider to the floor between the two stalls. I had the ramp removed, since she refused to load in a ramp trailer in the past, and had full height doors put on. This was all done at the factory. They did a lovely job.

I took delivery about a month ago, had better tires for forest roads put on, got it all checked out for our first camping trip with it, and everything looked great. Once she got used to loading in it, she actually refused to come out! She seemed to really like it. Backing out didn’t bother her, and she’d self-load, jumping right on, and no danger to me putting up the butt bar because she stayed on of her own free will. Everything seemed great.

Until it wasn’t.

She leaned so hard on the center divider that she actually loosened the screw holding the divider padding in place. The screw and washer ground into her hip. She got off the trailer after two hours with huge, bleeding gouges in her hip.

I removed the screw and glued on a piece of lambskin rug in its place, so she couldn’t cut herself again. Then, while she healed, I practiced trailer loading with her again–no problem. She self loaded and stayed on of her own volition.

With her wounds mostly healed, I felt it was ok to haul her today. Just as a precaution, I put a light raincoat on her, to protect her hip, in case she resumed leaning.

When we got home it was clear from the impression on the center divider pad that she’d been leaning very hard again. She couldn’t cut herself, and the blanket was unmarred, but the pressure she put on her hip split open her wounds again.

I really like this trailer–the configuration is perfect for what I do–but I am wondering if I really need to sell it instead of my old slant load.

Why is she leaning on the center divider now when she never did this in straight loads in the past? Does it mean she has some other issue that would cause her to have difficulty balancing?

What remedies could I try to make the Hawk work? Any ingenious ideas?

I won’t be able to get back what I spent on it because of all the custom modifications. And I still think the slant load is not going to hold up much longer and is would be dangerous in an accident. Do I go to a stock trailer?

Does anyone here have experience like this with a straight load, and did you find a solution?

Thanks, if you’ve read this far. Sometimes I have to type it all out just to get my own head around what I am dealing with.

It could be pain, I know a few horses that “leaning on the divider” is a sign to get their injections of choice done. You said she’s arthritic now, so that would make sense.

Also, can you switch her to the other stall? I’ve known more than one horse that can’t ride on the road side, only the ditch side. No idea why. I know you had your bars lowered for the mini, but it would be very simple to have a shop put attachments at horse height and mini height on both stalls. You could maybe do a trial run by stacking a bunch of hay bales in front so she can’t go over the chest bar? Alternatively, swing your divider over or take it out and let her ride in a “slant”, sans mini, and see how she handles that?

I have had two Hawk trailers (actually Equispirit) so am familiar with the two horse straight load/front tack. My suggestion would be to increase the padding on the center divider. You said “She leaned so hard on the center divider that she actually loosened the screw holding the divider padding in place.” --if this is a piece of padding put on at the factory, then what you have is a 1/4 piece of plywood, covered by 2" foam pad, held in place by upholstery grade vinyl. The capped screws should be about 3/4 inch with a plastic “washer” that holds a black button that snaps in. It would appear from what you said that the cap broke off and you replaced it with lambswool.

My suggestion would be to repad the center divider. You can probably still use the plywood --if not have one cut at the lumber store (I usually take the old one in so it will be exact). You might even consider making the pad longer to cover the entire divider (as I recall the pad stops about 6" to 1 foot from the back. I used “marine grade” foam and vinyl --like one uses for boats --readily available at fabric stores. I used a staple gun to attach vinyl over foam to board. You can buy the capped screws from Hawk, or on-line (I found it easier to buy from manufacturer). Because you are drilling into aluminum, not steel, a tap with a nail to set the screw and go for it, attaching the padding.

If all this sounds like too much ( I loved rehabbing old trailers and tried to make them look like they just came from the factory --or better), then just buy the foam and duct tape and WRAP the center divider in 3" foam.

My horse paws (I use bracelets, but don’t take chances) so I took a thin rubber mat, like one stands on in the kitchen, and wrapped it around the vertical center post in the front of the trailer. I wrapped thoroughly with an entire roll of (black) duct tape. Occasionally, I have to rewrap it if he wears a hole in the tape, but it thoroughly protects his inside leg. I have seen folks use pool noodles in various places: overhead where horse might bump head leaving trailer and on divider grid.

A thin rubber mat, long, like one might use for yoga might also work to protect your mare.

And I am sure you have thought of the obvious, hay in the trailer to keep her occupied.

I wish someone made bubble wrap blankets for hauling!!

Is maresy still willing to load? I agree with Foxgloves’ suggestion to wrap the divider more heavily. Maybe she just feels like she needs some support while traveling.
When standing for a long time I sometimes feel it would be nice to have something to lean on.

Good luck.

Hi,
Wondering about the divider that goes all the way to the floor? Does this horse find that too restrictive? Or does that for some reason invite the horse to lean?
I too would experiment, if possible, trailering horse on the other side.

Can you remove the divider and give her a fully open trailer again?

Sounds like a balance issue caused by either something neuro or pain. For my older guy, it was arthritis in his neck making it hard for him to balance while the trailer was in motion. After a bunch of tests and then cervical injections, ultimately he had to have an open trailer or use the last (bigger) slot of a slant load so that he could spread his legs wider to be able to balance.

I agree with this. Usually if they’re older, arthritic etc they need to really spread their legs in order to balance. Is there any way to test giving her that space to spread her legs?

I’d have a lameness exam done. My guess is that she’s uncomfortable and bracing.

Many thanks to everyone who has replied. You’ve given me a lot of ideas and information I didn’t have.

I did have a visit with her vet/chiro planned for yesterday, to get his assessment of why she might be leaning; unfortunately it had to be rescheduled. But she will see him soon, probably Monday.

I don’t think she is lame or suffering from anything that would show up on a lameness exam. Directly after driving her over bumpy roads for an hour (during which she was leaning on the divider), she didn’t take a bad step under saddle for many miles, carrying both me and about 30# of camping gear.

Previous to that, she was leaning hard on the divider on our way to my weekly riding lesson, and my teacher, who sees more than most vets–or anyone else for that matter–declared her perfectly fit for saddlepacking and ready for trot work. Astonishingly, her arthritis has ceased to affect her for the past year or so. A whole other subject for another day, but suffice it to say I’m having great success with my teacher’s protocol (she has cured several horses of ringbone and sidebone), and with a new hoof trimming philosophy.

But it also begs the question–if maresy hurts in this much smoother trailer, why doesn’t she hurt in the opened up slant trailer? With no support whatever she stands well without scrambling down horrifically bad roads in that trailer.

On to the big surprise for me: There are NO BUTTONS on the Hawk padding. All the screws are exposed. They are buried deep in the padding, so they wouldn’t come into contact with the horse unless it was pressing very hard on the pads. So–are there supposed to be buttons? If so, I am amazed the factory didn’t replace them. I am now wondering if they neglected to replace them when they did a deep cleaning of the trailer. I suppose I should call and ask.

The ditch side stall breast bar can adjust from riding horse to mini and back, so no issue there. If maresy rides better on the ditch side, I would just have to get a lower bracket put in in the other stall for the mini.

However, she mostly travels alone, and IIRR it is unsafe to haul a single horse on the ditch side–isn’t that right? Wouldn’t it unbalance the trailer because of how roads are canted?

Foxglove, I like your idea of repadding the divider, though what exists there now doesn’t fit your description of what it is like at all. The padding is very thick. There are no caps on any of the screws in either stall–they are just buried super deep in the padding. The screws and washers are metal and have sharp edges–I was really rather surprised by this. The pad already runs the full length of the divider. I took the offending screw out entirely and filled the resulting depression with the lambskin rug piece, using Gorilla glue. The threads in the hole for that screw are stripped and won’t hold any more.

So, wondering if Hawk owes me the caps? I am a bit hesitant to call as I already called in a warranty on the wheel bearings, which were supposed to have been greased, but were not. Or at least, not sufficiently. I was reimbursed, but under protest.

Colorfan, maresy does load. There is always hay in there, though I believe she would load for me even without hay. We have a very trusting bond. But this whole situation has me worried I will lose that trust. As mentioned earlier, she balances herself just fine facing backwards in a wide open slant turned into a stock.

Unfortunately if I were to take out the divider and use the trailer as a stock, there are some safety issues–no place to tie her head, no way to keep her separate from the mini—I’m basically back to where I started with the old trailer.

I don’t believe the center divider that goes to the floor is causing issues–it’s a flexible rubber mat that is removable, hanging from the center divider, and it is easily pushed aside just from the movement of the trailer. It is just enough of a barrier to keep the mini from ending up under the divider, but I don’t believe impedes maresy’s ability to spread her feet at all.

Mmeqcenter, your hunch is what concerns me also. She will get a thorough eval by the chiro/vet on Monday morning, and I’ll also have him look at the trailer. He will know if she’s having the kind of problem you mention. He has helped me solve so many of these kinds of problems in the past, from saddlefitting to hoof trim.

Again, thanks so much everyone for your thoughts and suggestions. If anything else comes to mind, please do post it.

I agree with changing the divider to one that is open at the bottom so she can spread her legs wide. When she travelled in the open trailer she probably stood with legs wide to keep her balance.

Excuse me if already posted. Do you have a trailer camera and monitor things as you tow?

You don’t have to answer but some things to think about.

  • Do you have a camera in the trailer to watch her? If yes, do you have videos of her in a straight vs slant vs backwards, vs open box?

  • It does sound like a pain or neuro thing. Not to be that person, but your trainer didn’t cure ring or side bone unless she surgically went in a removed the calcium deposits (and even then). Just because your trainer doesn’t see something doesn’t mean there isn’t something there.

  • Are the shocks (springs) on the Hawk new?

  • Can you remove the divider on the Hawk and give her the open stall in that trailer?

  • How are the shocks on your truck? Bad truck suspension can transmit more to the trailer.

  • A Shocker hitch or similar may be helpful on the rough roads. Ditto for a weight distribution hitch and Sumo Springs.

I had one mare that loved to sit all her weight on the butt bars. She may feel more secure leaning her weight on something. Is she facing forward or backwards when she leans on the divider?

Mallard,
If the rubber divider on the bottom is the problem, I’m going to have to sell the trailer. I can’t risk the mini ending up under the divider.

I do have a backup camera I can put inside the trailer to see what is going on. I will do so the next time I put her in there.

My camera doesn’t make videos

You are being that person. There is plenty science hasn’t yet figured out. Even more that veterinary medicine hasn’t figured out. Four years ago my vet told me it was time to find a new horse, that my horse would never be able to be ridden on trails ever again due to arthritis. Today, he has pronounced her perfectly sound. No injections. No surgery. On her lameness exams “she doesn’t take a bad step.” She is back to doing very aggressive mountain riding in rugged terrain. She is very happy, enthusiastic, and forward under saddle–and peaceful/calm. I do keep her in padded boots to minimize shock on hard, rocky ground–and in the trailer.

The Hawk has torsion axles, not leaf springs. I had them inspected and was told they were in perfect shape. The old slant load has much worse suspension than the Hawk, and she didn’t have a problem with that trailer.

The divider is removable, but then I have no place to put another horse, or my mini.

The truck is 20 years old and could probably use new shocks. While this may affect the trailer, it also then had to have affected the old slant load. Which didn’t bother my mare.

Thanks for the hitch recommendations. I’ll definitely follow through on those suggestions. However, it’s the same truck and setup with the Hawk as it was with the old slant load. Same hitch, springs, suspension in the truck, etc.

I had one mare that loved to sit all her weight on the butt bars. She may feel more secure leaning her weight on something. Is she facing forward or backwards when she leans on the divider?

She is facing forwards. There is no safe way to have her face backwards in this trailer. Part of my concern is that she has learned to enjoy riding facing backwards, and now won’t accept anything else.

I was talking tonight with a friend who has a Trail-Et–basically the same trailer. As we brainstormed over what could be going on, we both realized at once that the amount of force my mare would have to exert to carve herself up like she did is not just leaning for support—it has to be actual, forceful pushing. Maresy isn’t leaning, she is actively trying to bust out of that trailer stall. I now suspect this is a psychological, not a physical issue.

I talked to the seller of the trailer–a longtime dealer and trailer designer–and he said he has never heard of a horse doing this to themselves in any of these trailers–the screws are just set too deep for the horse’s body to contact them. (They do not have caps or buttons over the screws and never have.)

Unless, of course, horse is pushing incredibly hard. Like maybe she did when she was trying to bust out of the slant load stall by putting her feet against the wall and throwing her whole weight into the divider.

So a watch with the camera is in order.

It doesn’t sound psychological to me. It sounds like she is uncomfortable standing facing straight forward without the ability to spread her legs due to the divider going all the way to the floor. Which isn’t at all unusual, even for perfectly sound, healthy horses.

I know you thought this was your dream trailer, but your horse is telling you otherwise. Can you borrow a stock trailer to see how she rides in there? My bet says she will be much better if she can travel loose and backwards.

Yes, this. Horses that are trying to get out tend to go forward over the chest bar or out a window. Leaning on a divider heavily enough to cause such an injury is NOT normal.

It is VERY common for horses to scramble/lean/have issues with dividers that go to the floor. The reason she was okay with trailering in the old rig was because she could stand with her legs wider, and also facing backwards has been correlated to less stress and fatigue.

The camera is a good idea. Heck, you can tape a phone or GoPro up there to video, and just take her on a trip to the local park and back. Try to recreate some of the road conditions if possible. Best practice would be to also film her loose in a box stall for comparison.

A stock combo with a cut gate to make 2 boxes would solve these problems, if it comes to it. Well, it won’t fix whatever is bothering her physically, but it may make her comfortable enough to trailer happily again.

What is the flooring in the Hawk? My horse hauls very well…for a short time I had a trailer w WERM flooring. It’s supposed to be the bee’s knees but no one told him. He would scramble on turns. I think that flooring was hard and slippery to him, even w bedding.
