A saddle is fitted to a shape, and the shape does not stay. Weight, season, muscle and workload all change a horse's back, which is why a fitting is a snapshot, not a certificate.
The Society of Master Saddlers advises a check by a qualified saddle fitter at least every six months, and as often as every two to three months where a horse is changing shape quickly: youngsters, horses coming back into work, horses gaining or losing condition.
That is not an invented service interval. Research measuring horses' backs found they change measurably over a period of work, which is exactly why a saddle that fitted in spring may not fit by autumn.
In a study of 506 sport horses that their owners considered sound and in regular work, roughly one saddle in five showed uneven contact over the back, and around a third sat out of balance. These were not neglected horses. They were horses whose owners had no idea, which is rather the point.
A saddle that keeps slipping to one side is usually read as a saddle problem, or a crooked rider. The research says otherwise: in one study the saddle slipped consistently to one side in 54 percent of horses with hindlimb lameness, against 4 percent or less of other horses. A slipping saddle is more often a sign the horse is not right than that the saddle is. If yours keeps slipping, the first call is the vet, not the saddler.
Six months is long enough to forget all four. That is not a character flaw, it is how memory works over months. It is also precisely the interval where a written record starts paying for itself.
