We know that Dachshunds are prone to back issues, but if the x-ray was clear I can not think of another cause without examining Mollie; myelography may be useful to see if the
vertebral canal in more detail in case there is an
abnormality.
Gait
abnormalities, such as ataxia, paresis, or paralysis, may be present if secondary spinal cord or nerve root compression occurs.2 When neurologic signs are present, they correlate to the location of the discospondylitis lesion; cervical
vertebral column lesions may cause tetraparesis and neck pain; thoracolumbar lesions may cause pelvic limb paresis, proprioceptive ataxia, and back pain; and lumbosacral lesions may cause a stiff, stilted pelvic limb gait.1, 2 Discospondylitis can affect any area of the
vertebral column, but the most commonly affected sites are L7 to S1, caudal cervical, mid-thoracic, and the thoracolumbar spine.
