Safety notes
Needling should only be done by a trained veterinary professional. This point lies along the back or hip region, close to deeper structures such as the kidneys or sciatic nerve, so needle depth is chosen with care. Cautions in the source atlas: Risk of pneumothorax.
Some owners are shown gentle acupressure by their veterinarian. Do not press on a painful area, and stop if your dog shows pain, guarding or anxiety. If your dog suddenly cannot walk or is in severe pain, see a veterinarian immediately.
