title: Degenerative myelopathy in a German shepherd.
abstract: A 9-year-old male German Shepherd had marked stumbling, staggering and weakness in both rear limbs. Pelvic radiographs revealed only mild hip dysplasia, while survey spinal radiographs and a myelogram revealed only areas of possible pachymeningitis. Results of CSF analysis were normal. Degenerative myelopathy was suspected, but a mitogen response assay failed to confirm this diagnosis. Another mitogen response assay, performed several months later, again failed to indicate degenerative myelopathy as the cause of clinical signs. The dog's condition worsened and the animal was euthanized. At necropsy, classic histopathologic lesions of degenerative myelopathy were noted in the thoracic spinal cord.
