A 1.6 kg, six-week-old Tibetan Terrier was admitted with a 12-hours history of acute onset of progressive tetraparesis following insertion of a microchip to the dorsal cervical region. Neurological examination indicated a lesion to the Ce(1) to Ce(5) spinal cord segments. Radiographic examination confirmed the intra-spinal location of a microchip foreign body at the level of the second cervical vertebra. Microchip removal was achieved following dorsal hemi-laminectomy; significant intra-operative haemorrhage was encountered. The puppy was ambulatory at day seven. Follow-up telephone interview 18 months postoperatively confirmed that the patient had made a good recovery although it had a mild residual right- sided torticollis.
