Plain-English summary
A 9-year-old mixed-breed dog was brought in with signs of weakness on one side of its face, which was caused by a stroke affecting the trigeminal nerve responsible for facial movement. Thankfully, the dog did not experience complete paralysis, and the veterinarian noted changes in the nervous system that could help with future diagnoses. While the dog’s condition was serious, the focus was on understanding the underlying issues rather than treatment, as the case highlighted the need for thorough examinations after such neurological events.

Abstract
An unusual case of unilateral trigeminal neuronopathy in a dog is reported, in which the motor nucleus of the trigeminal nerve and the ipsilateral corticospinal tract were destroyed, apparently by a cerebrovascular accident (stroke). Hemiplegia did not occur. Neuropathological changes are described, including remyelination by Schwann cells in the central nervous system. The case illustrates the importance of central nervous system post-mortem examination when establishing causes of cranial nerve paralysis.
