A 4-year-old female spayed Pomeranian presented for being unable to use its pelvic limbs after a fall. The dog was paraplegic with absent pelvic limb nociception and a Schiff-Sherrington posture. Radiographs and Computed tomography showed a T11-T12 luxation. Spinal stabilization was performed for pain control. Twenty-four hours following surgery the patient lost pelvic limb reflexes. Twelve hours later she lost cutaneous trunci and forelimb proprioception and had increased respiratory effort. A diagnosis of progressive myelomalacia was made and the patient was euthanized. Most cases of progressive myelomalacia in dogs are due to intervertebral disc herniation. To the authors' knowledge, myelomalacia secondary to spinal fracture has not been reported.
