The right instinct, at the wrong time: why we almost always call the vet too late
There is a moment all owners know well. The horse is “a little short” at the trot, nothing more. Nothing clear-cut. You tell yourself you’ll check again tomorrow. Tomorrow, it’s better. Three weeks later, the vet prescribes six weeks of rest.
It is not a matter of negligence. It is a threshold problem: between the moment something starts and the moment it becomes visible, several days often pass. And during those days, the only instrument the rider has is their hand.
Hence the question that keeps coming up in the stables: when should we call? Too early, and you're disturbing someone for nothing, with the visit still costing the price of a consultation. Too late, and you pay for it in weeks of stall rest. In between, for a long time, there was only intuition.
What a thermal camera changes in this specific decision
Thermography is nothing new in equine medicine: clinics have been using it for years. What is new is that a device sensitive enough now fits into a grooming bag.
The principle is simple. An infrared sensor measures surface temperature, point by point, and translates it into an image. Where the hand perceives "hot" or "not hot," the device displays a number.
Watch: a figure instead of an impression
Vigie is a thermal camera designed for equestrian use. Its sensitivity goes down to 0.04°C. It does not replace your hand: it gives it a scale.
Its main value lies in one specific function. The device analyzes the entire image and automatically marks the hottest point in the targeted area, with its temperature displayed on the screen. You aim at the left forelimb, you note the number. You do the same on the right. You have two values to compare, and that is all serious monitoring requires.
No color nuances to interpret, no settings to search for. This is what makes the device usable by someone who has never done thermography before.

So, when should I call?
There is no universal threshold, and one should be wary of anyone who provides one. What thermal monitoring provides is not an automatic answer: it is an objective element to weigh in the balance, alongside what you see at work and what you know about your horse.
In practice, the method consists of four rules. You must always photograph both sides, in succession, at the same distance and under the same conditions: horse dry, rested for twenty minutes, sheltered from wind and direct sunlight. You record both values. It is the difference that tells the story, never the absolute value. And you date each series, because a single image is not worth much, whereas two images of the same back taken three weeks apart say a lot.
A marked difference between two equivalent areas, which is confirmed from one session to the next, is a serious reason to pick up the phone. A difference that disappeared the next day was probably the sun, a blanket removed ten minutes earlier, or dried mud on a cannon bone.
We must be clear about the limit: Vigie does not diagnose anything. It measures surface temperatures, nothing more. It does not detect inflammation, predict lameness, or say what a horse has. What it does well is give you an objective reason to call your vet sooner, or not to call them. Over a season, that is already a lot.
Each device comes with an equine thermography guide in French: the shooting protocol, the five zones to photograph in order, three commented examples of symmetry reading, common pitfalls, and a printable tracking sheet. It is this guide that makes the difference between a device that stays in its case and one that is taken out every two weeks.

A thermal image is only meaningful when interpreted in its context: the previous day's exertion, the weather, a blanket removed a few minutes earlier, or dried mud are enough to alter what you observe.
