Overview

Changes in the lower spine can narrow the space around the nerves leading to the back legs and tail. This narrowing, called stenosis, can press on the nerves and cause lower-back pain, weakness or lameness. Bulging disc material and thickened ligaments can contribute. Some dogs also develop a weak tail or lose normal bladder control, although pain may be the main problem.

Signs to watch for

  • Pain in the lower back
  • Difficulty using the back legs
  • Limping on a back leg
  • A weaker tail
  • New urine accidents or loss of bladder control

Signs typically start between three and seven years of age.

When to get help Arrange a vet visit for lower-back pain or difficulty using the back legs.

Diagnosis and tests

Vets examine the lower back for pain and assess leg strength, reflexes and other signs of nerve dysfunction. X-rays may show age-related changes, but they do not confirm the diagnosis on their own. MRI or CT scans are used to identify narrowing and nerve compression.
