I’ve been working with horses for over 35 years, and one thing I see almost every single time is this: bit fitting for horses doesn’t get treated as routine care. It’s not on the checklist alongside the vet check, the saddle fit, or the dentist. It sits somewhere in the background, and most people only think about it when they’ve run out of other explanations.
And I completely understand why. But by that point, things have often been unravelling for a while.
So let me tell you about the calls I get most often.
The horse showing resistance
Everything was fine, and then gradually, or sometimes quite suddenly, it wasn’t. He’s getting tense in the contact, arguing about going forward, or throwing his head. The trainer has had a look. The physio has been out. The saddle has been checked. And still something isn’t right.
By the time someone calls me, they’ve often spent months trying to fix it, and the bit hasn’t been looked at once.
The new horse with an inherited bit
Someone has bought a horse, inherited the bit that came with it, and carried on. Which is completely understandable. If the previous owner used it, it must be fine, right?
Not necessarily. A bit that suited that horse at that time, ridden by that rider, may not suit the horse now. Mouth conformation varies enormously between individuals. What fits one horse well can be completely wrong for another, even if they’re the same breed and the same size.
The bit that was recommended but never properly assessed
A friend suggested it. A trainer swore by it. Someone on a Facebook group said it worked wonders for their horse. And so it went in, and it’s been in ever since, without anyone actually checking whether it fits that particular horse’s mouth.
Recommendations are well meant, but bit fitting for horses is not one size fits all. Not even close.
The horse that has never quite gone right
This is the one that stays with me the most. Not dramatically wrong, not obviously resistant, just never truly comfortable, never truly through, never quite reaching the contact the way you’d hope.
These horses get labelled as tricky, or green, or just one of those horses. Sometimes they’ve been like it for years. And when I get there and look properly at what’s in their mouth and how it sits, the answer is often staring us both in the face.
Bit fitting for horses should be part of your routine
It doesn’t have to be a last resort. A horse’s mouth changes over time. Muscle development, dental work, age, and changes in the way of going can all affect what works. A bit that fitted well three years ago may not be the right choice today, and it’s worth checking in regularly, just as you would with teeth or saddle fit.

Frequently Asked Questions
How do I know if my horse’s bit fits properly?
A well-fitting bit sits comfortably in the horse’s mouth without pinching, pulling, or creating pressure in the wrong places. The cheek pieces should support the bit when contact is taken up. Signs that something may be off include resistance to contact, head tossing, tension in the jaw, reluctance to go forward, and general unhappiness when being tacked up. A professional bit fitter will assess the horse’s mouth conformation, the action of the bit, and how it interacts with the horse’s way of going.
How often should I get a bit fitting for my horse?
As a general guide, it’s worth having a bit fitting review any time there’s a significant change. That includes getting a new horse, returning to work after a long break, changing discipline, after dental work, or if your horse’s topline and musculature have changed noticeably. Even if nothing obvious has changed, a check every year is sensible. A horse’s mouth is not static, and what worked well previously may not still be the right choice.
Can the wrong bit cause my horse to be resistant?
Yes, and this is one of the most common things I see. Resistance, tension, and training problems that seem hard to explain are very often connected to discomfort in the mouth. The difficulty is that horses can’t tell us where it hurts, so the signs often get misread as attitude or a training issue. Before assuming the problem is behavioural, it’s always worth ruling out physical causes, and the bit is one of the first places to look.
What happens during a bit fitting appointment?
A professional bit fitting starts with looking at the horse’s mouth conformation, including the shape of the bars, the tongue, and the palate. From there, the bit fitter will assess what is currently being used, how it sits, and whether the action suits that individual horse. Depending on what’s found, adjustments may be suggested or alternative bits trialled. The aim is always to find something that is comfortable for the horse and works for the rider’s needs.
Does bit fitting matter if my horse seems fine?
It does, for the same reason dental checks matter even when a horse isn’t showing obvious pain. Horses are remarkably stoic and will often continue working through low-level discomfort without obvious signs. Routine bit fitting for horses means you’re not waiting for a problem to develop before you address it. It also means you have a baseline to work from if things do change.
