What is one key to managing lameness?
Foot Trimming
What are the 5 points to the Dutch hoof trimming method?
- Measure and trim 1st claw (Medial in hind, external in front)
- Match trim to opposite foot

7.5mm or 3 inches
80mm
52 Degrees
Why is dishing out the center helful?
Weight is transferred from the center of the sole to the wall, toe and heel
