The vertebral arteries, as the first branches from the subclavian arteries, normally enter into the transverse foramen of the sixth cervical vertebra in dogs. This case report presents the nonstandard course of the left vertebral artery and unilateral asymmetry of the sixth cervical vertebra in a 14-year-old female mixed breed dog.

The anomaly was an incidental finding during the preparation of a corrosion cast prepared for educational and scientific purposes. The left sixth cervical vertebra transverse foramen and the ventral lamina were not developed.

The left vertebral artery originated normally from the left subclavian artery, but atypically entered into the transverse foramen of the fifth cervical vertebra. On the right side, the anatomical structures of the sixth cervical vertebra and the course of the right vertebral artery were normally developed.

To our knowledge, this is the first case of such an anomaly described in a dog.
