The Right Trailer for your Horse

You’re committed. You took the plunge. You have bought your first show horse and are now ready to reach your goals together. The trailer you currently have suited your other horse just fine, but what about this new guy? What if he has never loaded into a slant-load trailer or used a ramp to get in? USRider takes a look at some of the important questions you should consider when purchasing a new trailer.

Almost everyone has come across a horse that does not willingly load into a trailer. For a lot of horses, loading and unloading is the most stressful part of trailering. Making this a central consideration when you buy your new trailer can be imperative for your horse.  Some trailer features can make a big difference when it comes to the ease of loading and unloading.

Food for thought (or comfort): Will your new horse travel calmly and comfortably in a slant- or straight-load trailer? A two-horse straight-load trailer is fairly uncommon these days. A slant-load trailer is a more “modern” buy. However, if you have a horse that has been loading into a straight-load trailer his whole life, you may run into a few barriers (and headaches) if you settle on a slant-load trailer. In many slant-load trailers, horses can be turned around inside and be led out, easing some of those unloading fears. Three- and four-horse slant-load trailers with a large tack room at the front are the most popular among recreational and competing riders. However, if the horse in the front stall has a problem, all horses must be unloaded to get to that horse unless you have an emergency side door.

When looking into the purchase of a two-horse straight-load trailer, consider the size of your horse. For example, if you have a large Irish Sport Horse, a straight-load may be a poor choice because it will make for a tight squeeze. If you have a smaller breed, like a Quarter Horse, he will fit comfortably and experience less stress. However, a straight-load trailer allows for more neck room and also allows for each horse to be unloaded without disturbing the other. With that said, there are arguments that a straight-load trailer is better for a larger horse as he is able to stretch out more. You be the judge. Sometimes going as far as measuring can be a big help!

So which is better suited for your new companion? Opinions vary when it comes to the experts. A few companies including Sundowner, Featherlite, Hart and CM Trailers offer both designs; however, many customers prefer the slant load. There are some arguments that a straight load is better for your horse as he does not have to balance at a slant and allows him to use both front and hind feet evenly when loading and unloading.  Ramps can solve problems if your horse is not comfortable stepping up into a trailer.

There is a big difference in two-and three-horse trailers as far as hauling preferences. A two-horse bumper-pull trailer is much more stable than a three-horse bumper-pull. If you’re committed to a three-horse trailer, it is highly recommended by experts that you choose a gooseneck style as it creates better stability for handling that amount of weight.

A few creature comforts to consider: Windows within reach. Trailers are generally very tall with some window and door latches hard to reach. Some companies, such as Sundowner have moved these latches to the bottom or their drop down windows for better accessibility. When looking for your new trailer, make sure to check how each door locks. Many door handles will have deadbolt locks. This can be a big problem when you are fiddling with a key while trying to get to a distressed horse inside. Deadbolts should only be seen on tack and dressing rooms. Make sure your trailer is welcoming. The larger the windows and vents the better; along with inviting interiors, such as dividers that swing to the side and removable rear posts. They appear more open and roomy to a horse and not like they are walking into a cave where something is waiting to eat them.

One last note: Make sure there is good lighting inside your trailer for your horse(s). This is especially important if you are traveling at night and have to stop and unload your horses to stretch their legs. Loading them back in the trailer may become a headache if you do not have lights.

10 Tips for Hot Trips

Planning a summer trip that involves a long haul? Learn what it takes to keep your horse safe on the road when temperatures soar.

An important show, a destination trail ride, a permanent move that involves transporting your horses…whatever the reason for the ride, you and your horse are facing a long-haul road trip. Not only is it a long way to go, but you’ll also travel in summer weather, i.e., the hottest time of the year. How can you minimize the risks of hot-weather travel to ensure that your horse is safe, and that he arrives in top-notch form when it really counts?

You’re smart to ask, because trailering horses is always risky. Every time you load a horse in that little metal box, close the doors, and head down the road, he could stress out, hurt himself, or end up sick. And when temperatures soar, risks increase. I’m going to explain the added risks of hot-weather travel so you’ll understand what you and your horse are up against when you travel in the heat. Then, I’ll give you 10 time-tested tips to help you keep him safe.

Oh So Hot
To help you understand the risks, let’s start by looking at the basic mechanisms that help your horse cool down—and how those cooling strategies are compromised when he’s locked in a box.

Convection: Heat is carried away from your horse’s body as air flows over his skin, as in response to a cool breeze or fan. Often, airflow in a horse trailer is severely limited, especially if it’s standing still (picture a breakdown or other long wait on the freeway). If there’s no air movement, your horse’s ability to use convection to cool is completely lost.

Heat is lost into the environment because of a difference in temperature between your horse’s body and the surrounding air. When your horse is loaded in the trailer, his body heat goes no farther than the trailer walls. Simply put, there’s nowhere for the heat to go. With other horses in the trailer, this problem just gets multiplied.

Heat is lost when liquid is converted into a “vapor” in the air; this is the mechanism that occurs when your horse sweats. Sweating is your horse’s most important cooling strategy. Have you ever unloaded your horse on a hot day, only to discover that the interior of your trailer feels a little like a sauna? Your horse’s sweat is trapped in that air, and when the air is filled with moisture, your horse stays wet. Evaporation can’t help to keep him cool.

Conduction: When your horse’s warm body comes into contact with something “cooler” (like a spray of cold water or an ice bag), the heat transfers to the cooler object. Unfortunately, the inside of a trailer is likely to be hot, and hot divider walls won’t help cool him down.

Now let’s look at your horse’s own functions. When it’s hot, a number of physiologic changes occur to allow his heat-loss mechanisms to work. These changes transfer heat from his core to his body surface, so that the heat can be lost into the environment.

First, his heart rate increases, and the tiny blood vessels in his skin and the lining of his respiratory tract become enlarged. This improves blood flow to his periphery to aid heat loss via radiation, conduction, and convection. This transfer of blood flow means that blood is being shunted away from his vital organs, including his brain. Your horse may start to breathe more rapidly, or “pant,” allowing increased amounts of cooler outside air to pass by the blood vessels in his nasal passages. Finally, he’ll begin to sweat to take advantage of evaporation. When he sweats, fluid from his body will be lost. This compromises blood flow and makes it even more difficult for your horse to cool himself. A vicious cycle begins.

When your horse can’t cool down, these physiologic mechanisms go into overdrive. His heart races, his breathing becomes very fast and shallow, and he sweats profusely. Eventually, he becomes dehydrated—compounded by the likelihood that he won’t drink while on the road. In severe cases, blood flow to his vital organs completely shuts down. Heat stress, or even life-threatening heat exhaustion can result.

10 Hot-Travel Tips
What can you do to ensure that your horse can make the most of his basic cooling mechanisms? Employ the following time-tested tips.

1. Plan ahead. Know exactly where you’re going, plotting the coolest, most efficient route to get there. Check DOT (department of transportation) Web sites for updates on construction-site detours and delays. If you’re planning overnight stays, be sure you have current directions. Getting stuck or lost on the way to your horse’s “hotel” means extra time in the trailer—and the less time he spends in the trailer the better, especially when it’s hot.

2. Prepare your paperwork. Be sure you have the appropriate travel papers in hand before you leave for your trip. Few things are worse than arriving at a border crossing, only to find out you have to wait for the local vet to arrive and inspect your horse before you can continue down the road. Oh wait, there is something that can make it worse: waiting at a border crossing when it’s very hot. Can it really happen? You bet it can. In fact, one of our Olympic team members had to cool his heels for several hours just weeks before the Games, all because of a paperwork debacle. To avoid watching your horse bake in the trailer because of paperwork problems, call your veterinarian well in advance to find out what you need, and make sure it’s all in order before you leave.

3. Set your alarm. The time of day you choose to travel can really make a difference—so plan to get an early start! Many seasoned long-distance haulers will load up and hit the road in the wee hours of the morning, when it’s nice and cool. Depending on your destination, try to plan your travel schedule so you’ll be hauling through the hottest areas when it’s cool, and resting, horses safely unloaded, when it’s hot.

4. Go naked! Resist the temptation to wrap your horse in clothing before you load up. Naked is best! Remove blankets, coolers, and even scrims or “anti-sweat” sheets. If it’s very hot and he’s an experienced and stable traveler, this may even be a time to forego protective boots or bandages on his legs. The more of his skin that’s exposed to the air, the better off he’ll be.

5. Open up. Open every possible vent and trailer window (those with bars or screens) to maximize ventilation. Air movement is necessary for your horse to cool via convection. And by allowing the wet, hot air within the trailer to be exchanged with the cooler air outside, you’ll help your horse use radiation and evaporation more effectively.
6. Plan a fluid pre-load. Preventing dehydration is just as important as keeping your horse cool when hauling in the heat. He needs plenty of fluid in his system to keep his cooling mechanisms functioning well. To help him load up on moisture, consider giving him soaked hay, bran mashes, soggy beet pulp, or other wet feed sources for several days before you leave. If he’s notoriously bad about drinking on the road, you might even ask your vet about administering fluids via a nasogastric tube or IV catheter, right before you leave.

7. Boost electrolytes. Your horse loses electrolytes (a medical/scientific term for “salts”) when he sweats, and his electrolyte balance is important for his fluid balance and bodily functions. If you don’t administer electrolytes on a regular basis, consider adding them to your horse’s feed or water beginning five to seven days before you hit the road. If you add electrolytes to his water, make sure to provide fresh, non-electrolyte water as well, because many horses refuse to drink electrolyte water. And don’t make the mistake of just giving your horse a dose of electrolytes right before you leave. He needs time to drink enough water to balance what you give; otherwise, the electrolytes can actually cause him to become more dehydrated by drawing fluids out of his blood stream and into his intestinal tract. Commercial preparations of electrolytes are available in paste or powder form. If you want to make your own, you can mix three parts sodium chloride (normal table salt) with one part potassium chloride (“lite salt”) and give your horse two to four tablespoons per day.
8. Carry familiar water. Nothing is more stressful than an overheated horse that won’t drink. And you know what they say about leading a horse to water! If your horse is a fussy drinker, he might refuse to drink “funny tasting” water on the road. To circumvent this, carry plenty of familiar water from home. You also can consider adding a small amount of flavoring (such packaged lemonade) to his at-home water source for several weeks before you leave and use it once you’re on the road. This will allow you to mask unfamiliar flavors and might encourage him to drink.
9. Soak his hay. If you’re going to provide hay while on the road, consider soaking it to provide extra moisture. Not only will this help keep your horse hydrated, it’ll also minimize dust and help protect him against irritation to his respiratory tract that can also threaten his health when hauling. If he won’t eat hay, a twice-daily mash or ration of soaked beet pulp could also help.
10. Arrive early. Research has shown that your horse is likely to lose as much as a pound of bodyweight per hour during travel—even in ideal circumstances. That loss is likely to be more when it’s hot. To ensure that your horse is at the top of his game come competition time, plan to arrive at the venue with enough time to allow him to recover from his travels. As a rule of thumb, if your journey is 15 hours or longer, allow a minimum of three days to recover.
