Plain-English summary
Three young large-breed dogs, including a Dogue de Bordeaux, an Australian Bulldog, and a Boerboel, were brought in with serious neurological issues like trouble walking and even paralysis. They were diagnosed with a condition called cranial thoracic vertebral canal stenosis, which was causing pressure on their spinal cords. The dogs underwent a surgical procedure called unilateral hemilaminectomy to relieve this pressure. Most of the dogs started walking independently again within about two weeks after surgery, and while one dog had a setback months later, the other two showed significant improvement in their mobility and overall condition.

Abstract
OBJECTIVE: To describe the surgical treatment and outcome for juvenile dogs with cranial thoracic vertebral canal stenosis treated by unilateral hemilaminectomy. STUDY DESIGN: Case series. ANIMALS: Three large-breed brachycephalic dogs of various breeds (Dogue de Bordeaux, Australian Bulldog, Boerboel) with neurological signs consistent with a myelopathy of the third thoracic (T) to third lumbar (L) spinal cord segment. METHODS: Information on clinical presentation, diagnostic imaging, surgical procedures, postoperative complications, recovery and outcome is described. RESULTS: Neurological signs were present and progressive for two to four weeks prior to surgery and ranged from mild ataxia to paralysis. Cranial thoracic vertebral canal stenosis was diagnosed with computed tomography imaging. Lateral and dorsolateral spinal cord compression was present at multiple sites between T2 and T6. Alternating left and right-sided compressions were common. Surgical treatment was by unilateral, continuous hemilaminectomy over three to six vertebral spaces. Postoperative morbidity was minimal and return of independent ambulation was rapid (median: 13.5 days, range: 2-29 days). Neurological status in one dog worsened four months after surgery due to reoccurrence of osseous compression; unilateral hemilaminectomy was repeated in this dog. Long-term follow-up ranged from six to 10 months; neurological signs had completely resolved in one dog and substantially improved in the other two dogs. CLINICAL SIGNIFICANCE: Unilateral hemilaminectomy was associated with rapid return of independent ambulation and substantial improvement in neurological scores.
