A horse saddle is an essential part of the equipment for riding a horse. It is important that the saddle fits both the horse and the rider well for a comfortable and safe ride. The size of a horse saddle is determined by various factors, including the dimensions of the horse and the rider's body structure.

During training, a horse's back can change due to various factors such as muscle development, weight loss or gain, improved fitness, and changes in posture. Stronger back muscles provide more support and contribute to better balance and weight-bearing during riding. Weight changes can affect the fat layer on the horse's back and thus the fit of the saddle. Additionally, improved fitness can lead to changes in posture, such as a more elevated back, which requires adjustments to the saddle. Changes in posture during training can also affect the shape of the back and necessitate adjustments to the saddle.

It is important to regularly check the fit of the saddle, especially during the training period, as a saddle that does not fit well with the changing shape of the horse's back can cause discomfort and injuries. In situations where a horse's back changes, a saddle pad, also known as a saddle blanket or numnah, can be useful. A saddle pad provides protection to the horse's back against friction and pressure points that can arise from the saddle and girth. It can also provide additional padding to fill any gaps that may occur due to changes in the shape of the horse's back. This can create a better fit between the saddle and the back and reduce unwanted pressure points. A saddle pad can also serve as a temporary adjustment until a suitable saddle is available. Additionally, a saddle pad with specific features such as non-slip material or inserts with a raised back can help keep the saddle in a better position and prevent it from sliding forward or backward.

While a Sedelogic saddle pad can offer some benefits in situations where a horse's back changes, it is important to note that it is not a definitive solution for an ill-fitting saddle. It is always recommended to consult a professional saddle fitter or saddle maker to ensure that the saddle properly fits the changing shape of the horse's back and meets the needs of the horse and the rider.
