Degenerative myelopathy was diagnosed at necropsy of an adult Miniature Poodle with a 33-month history of progressive pelvic limb ataxia and proprioceptive deficit. Microscopic examination of the cord revealed diffuse degenerative myelopathy. Degenerative myelopathy is usually seen in adult, large-breed dogs and progresses over a period of months. In this case, the myelopathy progressed slowly and the degree of paralysis became more extensive than usually seen.

Degenerative myelopathy was diagnosed in a 6-year-old cat that had progressive ataxia, posterior paresis, and loss of conscious proprioception over a period of 8 months. Corticosteroid therapy did not alleviate clinical signs, and the cat was euthanatized. Microscopic examination of the spinal cord revealed diffuse degeneration of myelin attended by marked astrocytosis. The degenerative changes were most marked in the thoracolumbar segment. The cause of the degenerative lesions was not apparent.

Degenerative myelopathy was diagnosed in six Mongolian wild horses. Three of the horses had a history of ataxia dating from birth to 3 months of age. The clinical signs were uncoordinated movement of the hindlimbs and an abnormally wide-based gait and stance. The other 3 horses had mild ataxia. There were no gross lesions in the brain, vertebrae, or spinal cord. Histologic examination revealed degeneration of the neural processes in the ventral and lateral funiculi of all 6 horses. Myelin sheaths were dilated and vacuolated, and there were swollen, fragmented, or lysed axons. Neuronal degeneration, phagocytosis, and accumulation of periodic acid-Schiff-positive, xylol-insoluble lipopigment were observed in the affected neurons of the dorsal root ganglia. The plasma alpha-tocopherol values of 5 of the affected horses ranged from less than 0.03 to 0.08 (mean, 0.04 +/- 0.01) mg/dl. Seven clinically normal horses from the same herd had a range of less than 0.03 to 0.3 (mean, 0.11 +/- 0.02) mg/dl, which was low enough to be considered deficient.
