The scale and the six areas
Body condition scoring puts a number on a horse's fat cover using the widely used nine-point scale, where the lowest scores describe a genuinely thin horse and the top scores an obese one, with healthy riding horses generally sitting somewhere near the middle. The score is built up from six areas assessed in turn: the neck, the withers, behind the shoulder, over the ribs, along the loin and back, and around the tailhead. Each area is looked at and, more importantly, felt, because fingers find fat that a winter coat or a quick glance completely hides. An overall score blends the six, but a single area running high — a thick, cresty neck, for instance — is worth noting on its own.
How to score by hand
Work through the same areas in the same order each time, using the flat of your hand with firm, even pressure. Fat cover feels spongy and mobile over the bone beneath; muscle feels firmer and sits where working anatomy says it should. Over the ribs is the most telling test for most horses: at a good mid-range score the ribs are not visible but can be felt easily under a thin, smooth covering, while a horse you cannot feel ribs on at all is carrying far more than condition. Run a hand along the neck to judge how much crest wobbles, press over the tailhead where fat pads build early, and compare one side with the other — they should tell the same story. Score with the horse standing square on level ground, and in the same light and place each time if you can, so photographs taken alongside the numbers compare honestly month to month.
Why scoring beats guessing by eye
Owners are notoriously poor judges of their own horse's condition, because they see the horse every day and change creeps in too slowly to notice. A score is a fixed yardstick: a horse scored the same way by the same hands every few weeks produces numbers that can be compared honestly across a season. That trend is what should drive feeding decisions — another bale's worth of hay, a muzzle at grass, a balancer review — rather than a vague feeling that he looks a bit well. It also catches the opposite problem early, when a horse quietly loses cover under a thick winter coat that makes him look unchanged.
Scoring through the year
Horses are designed to gain on summer grass and ease back through winter, and a small seasonal swing is natural rather than alarming. What matters is the range: a horse who peaks at a sensible score on grass and returns to mid-range by spring is cycling healthily, while one who starts spring already fat and climbs from there is heading for trouble. Score natives and good doers more often during the spring flush, score older horses more often through winter when teeth, cold and mud all conspire against condition, and always score before changing a ration so you know whether the change worked. Keep those dated scores in your horse's KinsLe Pet Passport, and the pattern behind any weight change is there to walk through with your vet at the next visit rather than reconstructed from memory.
