Why I Choose a Double Bridle for Dressage but a Snaffle at Home
Anyone who has spent a decade plus chasing eventing ribbons around this country will tell you that bridles are rarely a one size fits all conversation. My own approach has shifted plenty over the years, often shaped by whatever horse is currently in the barn and whatever level I am trying to crack. The split between what I ride in the warm up and what I ride down the centreline has become one of the most asked questions at the clinics I help at, and it deserves a proper answer rather than a quick shrug.
At home, leaning on the fences of my property north of Sydney, I almost never reach for the double. It feels heavy in my hands after a long day in front of a laptop, and my horses read my mood the moment I tack up. Out at the events, whether I am heading south for Melbourne 3 Day Event or staying closer to home at Sydney Eventing or Wallaby Hill, the conversation changes completely. The test is the test, and the bridle has to match the picture I am trying to paint.
This is not a how to on bitting, and I am not the voice that settles the great snaffle versus double argument online. It is an honest look at why my routine looks the way it does, with all the wobbles and second guessing that come with it. If you are weighing up your own setup, take what fits and leave the rest in the sand school.
The Practical Side of Choosing a Bridle
A double bridle, for those who have not yet sat behind one, is essentially two bridles in one. A bradoon and a curb, paired on the same headpiece, working together to give the rider finer control of the head and neck. The snaffle, by contrast, is a single bridle with a jointed or unjointed mouthpiece that most of us learn to ride in long before we ever pick up a curb rein.
When I started eventing in earnest, I was at a Pony Club rally in regional New South Wales, riding a borrowed Thoroughbred who would have happily carried me to a ribbon in any bit. The snaffle did everything I asked of it, and we did not look much further. Progressing up through the levels, particularly once I started aiming at the higher Pre Novice and Novice divisions run by Equestrian Australia, the judge comments began to nudge me towards something with more polish in the picture.
That nudge is the heart of the practical side. At Elementary and Medium dressage, which is where many eventers meet their first formal level tests, the rules allow either a snaffle or a double. From Advanced and above, the option narrows considerably. Knowing your competition calendar in advance, whether that means pencilling in Sydney International Equestrian Centre for a winter qualifier or booking accommodation for the Melbourne International Three Day Event, helps you decide when the extra training investment is worth it.
Schooling at Home in a Snaffle
My home schooling is built around the snaffle because the snaffle tells the truth. A loose ring or a D ring with a plain mouthpiece will not mask any imbalance in my own body, and that is exactly what I want when I am teaching a young horse to carry himself in a correct outline. The double, by contrast, can hide a multitude of sins from the rider, which is not something I need help with.
Heat is part of this choice too. Most of my summer schooling happens in the late afternoon or early evening, when the New South Wales humidity finally drops enough that both of us can breathe. A double bridle adds weight on the poll and more tack for the horse to sweat under. In the cooler months I am less precious, but I still default to the snaffle unless I am specifically preparing for a test.
There is also the mental side of schooling. My horses settle into the work faster when I am not constantly adjusting two reins and a chain. I can focus on the transitions, the lateral work, and the half halts without fiddling. If a horse is starting to lean on my hand or get heavy in the contact, the snaffle gives me a clearer read on what is actually happening in the mouth and what is happening behind it.
When a Double Bridle Makes Sense in the Arena
The competition arena is a different animal, and so is the warm up. When I am heading down the centreline at an event like the Sydney Royal Easter Show or the Adelaide Equestrian Festival, I want every tool available to present the best possible picture. The double gives me a quiet way to ask for collection without leaning on the snaffle, which can look and feel harsh at the moment of halt or salute.
The curb rein acts almost like a volume dial. Small adjustments change the shape of the neck, lift the withers, and soften the jaw, all without the visible hand movement that the snaffle sometimes forces. For the half pass and the moments of collected work I am building towards, the second rein is invaluable. I still ride the bradoon more than the curb, but the curb refines.
Practically, I introduce the double at least six weeks before a test I plan to ride in it. The horse has to accept the heavier headpiece, the extra mouthpiece, and the change in pressure. The first session is short, often just walk and a little trot, and I build from there. By the time we are at the venue, the bridle feels like an old friend rather than a piece of new equipment.
The Mouthpiece Debate
The bit itself deserves its own chapter, even if I keep it short here. At home I ride most of my horses in a loose ring snaffle with a French link, which I find sits comfortably and encourages the horse to mouth the bit gently. For the bradoon in the double, I keep a thinner loose ring with a similar joint to keep the feel consistent between the two set ups.
The curb is where the real thought goes. I have ridden horses who went beautifully in a ported curb and others who preferred a straight or roller version. Working with a reputable Australian saddler, ideally someone who will come to your property and watch your horse move, makes a much bigger difference than ordering a generic curb online. There are brilliant local makers around, and I am a fan of the bespoke work that comes out of workshops in Victoria and South Australia.
Bit fit is also something I check regularly. A pinch at the corners of the mouth, a curb chain sitting too low, or a bradoon that has been pinched by the headpiece can ruin an otherwise willing horse. Every couple of months I pull everything apart, check the leather, and reassess. Sometimes a horse simply needs a slightly wider headpiece once they have put on muscle through the winter work.
Conditioning the Horse to Both Setups
Conditioning a horse to ride in two different bridles is a quiet skill, and one I have refined after a few trial and error seasons. The key for me has been keeping the cues consistent. The snaffle rein asks for direction, the curb rein asks for collection. That division of labour does not change whether I am at home schooling canter pirouettes or warming up at the Equestriad in Tamworth.
I also spend time in the snaffle on days when I am specifically working on self carriage, including the days when the cross country work is the goal. A horse that leans on the bit in the snaffle will absolutely lean on the bit in the double, so the basics have to be honest before anything else. On that note, I wrote a piece earlier this year on staying focused on XC, and the same principles of consistent contact apply here. You cannot outride a horse who has been allowed to duck behind the bridle.
Switching between bridles also needs to be uneventful. I do not want my horse to prick his ears the moment the headpiece with two buckles appears. To keep it boring, I occasionally hack out in the double on quiet days at home. Long rein work in walk, a stretchy trot, nothing fancy. By the time we are at a competition, the bridle is just another piece of tack rather than a signal that the work is about to get harder.
Adjusting for Heat, Humidity, and Travel
Australian conditions have shaped nearly every decision I make about tack, and bridles are no exception. Loading the float for an event in summer often means early mornings on the M1 to beat the heat, and the horse arrives with a damp neck and a damp saddle pad. Bridle choice has to factor in that the leather will stretch, the bit will sit differently, and the horse will be carrying more tension in his back than he would at home.
When the weather is properly warm, I sometimes ride my tests in a snaffle even if I have trained the double at home, just to give the horse one less thing to process. The opposite is also true in winter, where the heavier bridle feels less sweaty and the curb rein sits more steadily against a cooler bit. Reading the conditions honestly matters more than sticking to a rigid plan.
Travel itself is another consideration. There is a long stretch of road between Sydney and Melbourne, and another between Adelaide and most of the bigger country events. By the time I unload, I want my horse comfortable in whatever I have chosen, which is why I tend to do my final bridle adjustments at the truck rather than back at home. For anyone planning a busy season of cross country runs, I also wrote about taping for cross country, and the same care around routine applies to how we set up for the day.
If you are sorting out your own bridle plan for the season ahead, take a quiet afternoon at home and play with the options. Try your normal test in both set ups, watch the video back, and notice what your horse tells you with his ears and his tail. Then pick the bridle that lets both of you breathe, ride the picture you actually want, and trust the feel you have built together.
