Degenerative Lumbosacral Stenosis in Dogs (DLSS)

Filed Under: Neurology

Degenerative lumbosacal stenosis (DLSS) is a common disorder of dogs.  Other names to describe this condition include cauda equina syndrome, lumbosacral stenosis, lumbosacral disease, and lumbosacral instability.  This condition is due to compression of the end of the spinal cord in the low back or nerve roots as they leave the spinal cord heading toward the pelvic limbs, tail, anus and bladder.  Compression can be the result of an intervertebral disck protrusion/herniation ("slipped disk"), thickening of surrounding ligaments, instability in the spine or vertebral malformation.

DLSS is most common in the German Shepherd and other large breed dogs, especially working in dogs.  It is occasionally diagnosed in small breed dogs and cats.  This condition occurs in middle-aged to older dogs, typically around seven years of age.
