What really happens when we put a bridle on a horse? Does “bitless” automatically mean kinder, or can it create just as much pressure in different places? And how much responsibility do riders carry when it comes to equipment choices?

In this episode, I sits down with researcher Tracy Bye toexplore a growing question in the equestrian world: was's the true impact of riding bitless. Together, we unravel the science behind pressure, movement, and horse welfare, challenging long-held assumptions and opening the door to moreindividualized approaches.

From the hidden dynamics of bridles to the role ofrider balance, this conversation reveals why equestrianpractice must go beyond tradition and start embracing research, responsibility, and the individuality of every horse.

And for those curious about alternatives,stay tuned until the end, Tracy and I dive deep into the physics of hackamores and their hardware, breaking down how these tools actually work, and what riders needto know before using them.

Head shaking in horses is one of the most misunderstood and emotionally challenging conditions horse owners face. In this episode, we explore trigeminal-mediated head shaking, a complex neurological disorder where horses exhibit intense, seemingly unexplained reactions to environmental stimuli.

Our guest, Dr. Veronica Roberts, is a European and RCVS Recognised Specialist in Equine Internal Medicine, Senior Lecturer at the University of Bristol, and one of the world’s leading experts on this condition. With a PhD focused on trigeminal-mediated head shaking, Dr. Roberts brings a rare blend of clinical expertise and compassion to the conversation.

We discuss:

• What makes trigeminal-mediated head shaking so difficult to diagnose

• Common environmental triggers and why nose nets sometimes help

• The importance of careful behavioral observation

• Why treatment is rarely one-size-fits-all

• How research is shaping the future of diagnosis and care

• The emotional toll on owners, and the support they need

Whether you’re a veterinarian, a horse owner, or simply someone who wants to understand more about equine welfare, this episode offers science-backed insights, practical considerations, and heartfelt perspective.
