Degenerative Lumbosacral Stenosis in Dogs: Welfare Guide

Degenerative lumbosacral stenosis (DLSS) causes compression of the cauda equina nerve roots in large breed dogs, leading to tail pain, hindlimb weakness, and difficulty rising.

Key Facts

Welfare Considerations

DLSS causes chronic pain and progressive neurological dysfunction that significantly affects quality of life in working and active pet dogs. The characteristic pain on tail elevation — used as a screening test — reflects the neuropathic pain component of compression. Dogs may become reluctant to exercise, show behavioral changes from chronic pain, and eventually develop urinary and fecal incontinence if untreated. Welfare-centered management requires accurate staging of the condition, appropriate analgesia throughout, and timely surgical referral for those not responding to medical treatment.
