aka degenerative lumbosacral stenosis, cauda equina syndrome, or lumbosacral instability

 

Degenerative lumbosacral disease (DLSS) is a painful condition affecting the lower back where the spine meets the pelvis (L7–S1 junction).

 

In this disease:

- the disc degenerates,

- the joint becomes unstable,

- surrounding tissues thicken,

- and the nerves of the cauda equina become compressed.

 

This causes:

- severe lower back pain,

- hindlimb weakness,

- difficulty rising or jumping,

- reluctance to work or exercise, and sometimes urinary or faecal incontinence.

 

DLSS is especially common in: German Shepherd Dogs, working dogs, large active breeds
