Grant Moon

Grant Moon, CJF, AWCF was first introduced to the farrier profession as a young rider.  Inspired and supported by his father to be the best, Grant decided early on that he wanted to become a master farrier.  He apprenticed with Steve Langford, AFCL for 4 years with whom he competed on the Welsh team in Dublin where he finished 5th as an individual as a 3rd year apprentice.  In Ireland, Grant was introduced to legends of the American farrier industry, including Bruce Daniels, Vern Hornquist, Dany Ward and Randy Luickart, who spurred him on to U.S. competitions in Texas and California.  Grant is a certified journeyman farrier (CJF) and passed the DWCF with honours, becoming an Associate of the Worshipful Company of Farriers (AWCF). 

Grant is especially well-known for his impressive success at the World Championship Blacksmiths Competition in Calgary, Canada, winning a total of 6 times and a runner-up 4 times.  He has also won the American Farriers Association Mustad Specialty Forging and Capewell Cup, the Northern California Classic and individual shoeing honours at Stoneleigh International in 1985 and 2008.  He is a 5 time member of the Welsh farrier team, winning in 1985 and 2008, and a 4 time member of the American farrier team.  Grant has trained 3 apprentices, Chad Lee, Jason Smith and Nick Barham DWCF, who now have successful farrier practices. 

Mr. Moon has been a Mustad consultant since 1991 to help develop farrier products and provide clinics in developed and developing markets, including Mexico, Argentina, Brazil and Hungary.  Grant works to promote good farrier practice, whilst respecting local traditions and environments.  He is thankful for the vision of Hans Nillson, a previous director of Mustad, who believed the farrier was worth investing.  Grant is thankful for his many mentors and friends and wishes that all can enjoy the farrier industry as much as he has during his impressive career.

Lecture/Forging Demonstration: "Shoeing Made Simple"

Shoeing the performance horse has never been more demanding.  Professionals have an ever increasing responsibility to prevent injury, maximize performance or to create a level of comfort in older athletes.  Becoming a proactive farrier or veterinarian can only be achieved with a better understanding of hoof trimming protocols.  These include hoof mapping, coronary band graphing and techniques for de-stressing the hoof capsule so it can function optimally.  Once we have trimmed the hoof, the choice of shoes and the variety and combination of shoe features are almost limitless.  It is imperative to have a solid understanding of how shoe features work, how the hoof reacts to different features and whether or not the shoe is appropriate for the individual horse.  Grant’s lectures and forging demonstration will focus on simplifying the vast amount of available products while respecting shoeing fundamentals to benefit the sport horse.

Sue Dyson


We are honored that Dr. Dyson has agreed to be our first repeat Heumphreus speaker to highlight how far we have come over the past 30 years in our knowledge of equine foot lameness.  Dr. Sue Dyson qualified from the University of Cambridge in 1980.  As a Thouron Scholar, she completed an Internship in Large Animal Medicine and Surgery at New Bolton Center and then spent a year in private practice in Pennsylvania.  Dr. Dyson returned to Great Britain to take a position in clinical orthopedics in the Centre for Equine Studies of the Animal Health Trust, Newmarket where she is currently Head of Equine Clinical Orthopedics, a clinical referral service for lameness and poor performance that attracts clients from all over the United Kingdom, Ireland and continental Europe. 

Dr. Dyson was awarded a Fellowship of the Royal College of Veterinary Surgeons (RCVS) for a thesis entitled ‘The Differential Diagnosis of Shoulder Lameness in the Horse’ and the RCVS Diploma in Equine Orthopaedics by examination.  She was awarded a PhD by the University of Helsinki, is recognized as a ‘Specialist in Equine Orthopaedics’ by the Royal College of Veterinary Surgeons and is an Associate of the European College of Veterinary Diagnostic Imaging.  

Dr. Dyson is co-editor of Diagnosis and Management of Lameness in the Horse and co-author of Clinical Radiology of the Horse and Equine Scintigraphy.  She has published more than 220 papers in peer reviewed journals concerning lameness and diagnostic imaging and has lectured worldwide and is also a former President of the British Equine Veterinary Association.  Dr. Dyson is also a rider and British Horse Society Instructor, producing horses to top national levels in both eventing and show jumping.

Lecture: "Thirty Years of the Foot in Equine Veterinary Medicine"

It has long been recognized that the foot is the most common source of pain causing lameness in the forelimbs of horses of all types.  There are excellent descriptions of the clinical features of foot-related pain provided by pioneers at the beginning of equine veterinary medicine.  Over the 30 year history of the Heumphreus Lecture, we have seen many developments in the use of local analgesic techniques, and the advent of nuclear scintigraphy, diagnostic ultrasonography, digital radiography, magnetic resonance imaging and computed tomography.  Dr. Dyson will address how this progress has improved our understanding of the aetiopathogenesis of conditions causing foot pain, diagnosis of foot pain and management.  With a focus on the navicular bone, the collateral sesamoidean ligament, the distal sesamoidean impar ligament (collectively, the podotrochlear apparatus) and the deep digital flexor tendon, Dr. Dyson will explore the development of our current knowledge.
