WHY IS HOOF CARE IMPORTANT?
Regular/Therapeutic hoof care enables the horse to stay sound to complete the job it is being asked to do
Conformational defects pre-dispose a horse to injuries over the course of a lifetime, and proper hoof care can help manage/delay potential issues
Keeping horses on a schedule helps to catch problems early

WHY IS HOOF CARE IMPORTANT?
A horses foot travels 2 ½ times the speed of the horse – A thoroughbred may be traveling at 30mph, his foot is traveling at 75mph
The foot on a Thoroughbred racehorse will accelerate to 75mph and decelerate to 0mph, impact the ground and then accelerate to 75mph again – two to three times PER SECOND!

ENVIRONMENT
Wet environments produce soft, weak hooves
Horses kept in wet environments are prone to: Thrush: Infection of the tissues of
the frog
A naturally occurring organism inside the horse. When poop packs inside the foot the infection takes place.
Organism cannot tolerate oxygen – regular hoof picking can discourage thrush
Soft Tissue Injuries - from unstable ground

Dry environments produce hard, brittle feet
Horses kept in dry environments are more
susceptible to impact/concussion related injuries
Arthritis

CONFORMATION
Conformation determines movement
Is the result of bones, and their relationship to other bones
You cannot correct a horses conformation through shoeing, you can only manage it
* REMEMBER: Conformation predisposes the horse to certain types of injuries – farrier manages defects

WHAT IS A GOOD HOOF?
A balanced hoof free of distortions and pathology
A farrier’s ability to do a good job requires: Flat area
Dry area
Well lit area
Horse that stands perfectly still
Quality hoof material
An appropriate timeframe/schedule
Trimming Interval determined by: Rate of growth
Job
Issues/distortion trying to be managed

Laminitis/Founder

LAMINITIS/FOUNDER
Due to changes in the metabolism there is
inflammation in the laminae (LAMINITIS)
Velcro like connection starts to die
Coffin bone is no longer connected to hoof wall
Deep digital flexor tendon (attached to coffin bone)
tries to pull the foot up on the toe, but leaves the
hoof wall behind
Results in either rotation or sinking (FOUNDER)

THEN, WHY DO WE SHOE A HORSE?
If a horse can do the job it’s being asked to do without shoes, then don’t shoe.
Why might a horse not be able to do it’s job without shoes?
Sensitive feet – ouchy on work surface
Structurally weak feet – falling apart, thin soles
Weak tendons that need support
Support a conformational defect
Abrasive work/living conditions cause excessive wear
Protect a certain part of the foot
