Degenerative Spinal Stenosis in Dogs

Degenerative Spinal Stenosis in Dogs

Cost of Treatment: $2,400 to $4,500 for surgery; up to $100 per month for ongoing medication

What it is: Also known as lumbosacral stenosis, this painful condition involves the narrowing of the spinal column, which puts pressure on the spinal cord. Small and medium-sized dogs may be born with the condition, while certain larger breeds may develop it over time due to instability of the lower vertebrae or the protrusion of discs between the vertebrae.


  • Pain in mid and lower back regions
  • Lameness
  • Weakness in pelvic limbs, muscle wasting
  • Weakness in or paralysis of tail
  • Abnormal tail carriage
  • Fecal and urine incontinence in some cases

Treatment: Pain and swelling can often be reduced with anti-inflammatory medications. Surgery may be required in severe cases. Many pet insurance policies cover surgery, with some extending the coverage to congenital conditions and breed-specific conditions like degenerative spinal stenosis. Many plans additionally cover prescription medications.
