What are the 3 layers of the hoof?
Stratum externum
Stratum medium
Stratum internum
What are the 2 layers of the stratum internum?

~12m for the toe
Longer in a cold or dry environment
What are the normal forces acting on the equine foot?
- Tension directed towards wall laminate
- Tension from DDFT
- Downward compression from P2
- Upward compression from the sole
- Forces acting on extensor process (extensor branches of suspensory ligament, common digital extensor tendon)
What are the forces that make up the suspension system of the equine foot?
DDFT

Concussion during impact is transferred from the distal phalanx to the stratum internum
Forces: ____ is slightly depressed as it counters the downward force.
Sole is slightly depressed as it counters the downward force
Forces: The ____ acts with the _____ to support the inner structures of the foot and to dissipate the force on the _______ ________.
The frog acts with the sole to support the inner structures of the foot and to dissipate the force on the distal phalanx
Forces: The ________ _____ are compressed, forcing the blood into the ________ _______.
The venous plexi are compressed, forcing blood into the digital veins
Forces: The ___ ______ act as a hydraulic shock absorber.

What is the general rule for trimming vs horse shoes?
If the foot wears faster than it grows, it needs a shoe
Depends on: hoof growth, horn quality, traction, protection, owner preference
