Overview

A gap can remain in the bony roof of the spine when the vertebrae do not close fully during development. If only the bones are affected, a dog may have no signs. When the spinal cord is involved, back-leg function and bladder or bowel control can be affected. Some dogs also have abnormal attachments that prevent the spinal cord from moving normally.

Signs to watch for

  • Weakness in the back legs
  • Hopping with both back legs together
  • Leaking urine
  • Loss of bowel control
  • A dimple or unusual hair swirl over the lower back

Present from birth; problems may become apparent in early puppyhood, though some dogs have no signs.

Emergency Go to an emergency vet now if your dog cannot walk.

Diagnosis and tests

Vets use a neurological examination to assess back-leg function and bladder or bowel problems. CT scans can show the gap in the vertebrae. MRI provides detail about the spinal cord and its coverings, including tissue protruding through the defect or abnormal attachments that tether the cord.
