ST 36 The point is located half-way down the tibial crest on the lateral side and about 3 mm lateral to it. Insertion is to 2.5 cm depth and the direction is parallel to the long axis of the dog, and posteriorly.

In practice, to find ST36, you need to identify the tibial crest.
Identify the patellar ligament and then run down the length of the ligament and identify where it inserts into the top of the tibial crest. Then run your thumb and index finger down the tibial crest to identify its distal extent. Identify the halfway position on the tibial crest and then move laterally about 3 mm in a small dog and up to 10mm in a large dog. The point ST36 is located here on the belly of the anterior tibial muscle.
Insertion is up to 25mm in a large dog. The needle is inserted parallel to the ground, parallel to the long axis of the dog and posterior in direction.
Below are two more illustrations of the relationships of the structures of the anterior knee to the various points in the region.
