How to – Apply hoof block

Goal- Use the block to lift the affected foot off the ground so that the lame digit is not weight bearing and can heal. [This is not necessary if the sore digit can be kept off the ground with trimming.]

Step 1. Properly trim the healthy hoof

• The block should be perpendicular to the long axis of the leg; this means the heels have to be balanced.

Step 2. Pick the right sized block

• Plastic blocks are useful in high wear environments (eg sand). Generally thicker blocks are used.

Step 3. Roughen the foot

• Use a grinder to lightly remove the horn and debris.

Step 4. Dry hoof and block

• The foot needs to be clean and dry. Dry the hoof and block  with a heat gun.

Step 5. Apply glue to block

• Two part component clue

• Apply 1/8″ glue to weight bearing areas: to the toe triangle and along the wall; avoid the flexor tuberosity area

Step 6. Lightly press block on hoof

• Too much pressure will squeeze the glue out.
• Smooth the glue around the edges with a tongue depressor
• Ensure the block extends over the heel area; if excessive it can be trimmed back

Step 7. Check positioning and fix if needed

• Walking can be improved by using a grinder to create an angle to the block (roll over)

• Ensure the other digit is protected from weight bearing and that the entire block will be weight bearing. Adjust if needed. 

Step 8. Reassess in 4 -6 weeks
