Saddle fit is one of the most significant modifiable welfare factors for ridden horses, with poorly fitting saddles causing pain that affects behavior, performance, and long-term health.
Saddle fit welfare is often underestimated because horses do not stop working when their saddle hurts them - they continue but show behavioral signs of pain that are frequently misinterpreted as training or behavioral problems. The horse that pins its ears when girthed, is reluctant to go forward, or bucks may simply be in pain from a saddle that does not fit. The welfare response requires prioritizing saddle fit assessment by a qualified professional before attributing behavioral problems to training or temperament. Regular reassessment is equally important as horses change shape with fitness, age, and seasonal condition fluctuation. A saddle that fit well in summer may cause pain in winter when muscles have reduced.
