🔎 Why Saddle Fit Matters More Than You Think
This video shows a client’s pony who had started to show clear signs of discomfort under saddle:
• Bucking
• Resistance to move forward
• Difficulty engaging properly
After assessing the pony, it was clear the saddle was too long, sitting past the last rib and putting direct pressure on the longissimus dorsi — the largest and most superficial muscle along the horse’s back. This muscle plays a key role in stabilising and extending the spine during movement. Constant pressure in this area can quickly lead to muscle fatigue, tension, and spasm.
The saddle was also affecting the thoracolumbar junction, where the more rigid thoracic spine meets the more mobile lumbar spine. This transition point is essential for collecting, lifting through the back, and engaging the hindquarters. When compromised, performance drops — and behavioural signs like bucking or resistance often follow.
Using my experience and hands-on assessment, I noticed early indicators like rubbed hair over the back and reactivity to palpation. A dynamic assessment confirmed limited range of motion and discomfort. While I’m not a qualified saddle fitter, nearly 20 years of working closely with horses has taught me how to spot the physical consequences of poor saddle fit.
There were also signs of compensation through the nuchal ligament, which supports the head and neck and connects into the thoracic spine. When the back is sore, horses will often adjust posture through the poll, neck, and forehand — which creates a chain of tension throughout the body.
📌 Once the saddle was removed and manual therapy was introduced, this pony began to show clear improvements in both movement and comfort.
✅ Key takeaway: A poorly fitted saddle doesn't just cause localised discomfort — it affects the horse’s entire back chain, posture, and performance. If your horse is showing signs of discomfort or behavioural changes, it’s worth considering saddle fit as a contributing factor.
