Degenerative Lumbosacral Disease in Dogs: From Working Heroes to Family Companions

As a veterinarian specializing in sports medicine and rehabilitation, I see degenerative lumbosacral disease (DLSS) often, especially in active-duty and retired working dogs, such as military and police K9s. But DLSS can affect any dog, especially larger breeds and older pets. It is one of the most common causes of chronic back pain and mobility issues in dogs.

What Is DLSS?

DLSS, or degenerative lumbosacral stenosis, occurs where the last lumbar vertebra meets the pelvis. Over time, the discs, bones, and ligaments in this area can thicken, shift, or degenerate. This narrows the spinal canal and puts pressure on the nerve roots of the cauda equin—a, a bundle of nerves that control movement and sensation to the hind limbs and tail.

This nerve compression explains the clinical signs we see, which range from subtle performance issues in working dogs to significant mobility challenges in family pets.

Signs to Watch For

Whether you’re a pet owner or a trainer of working dogs, the signs of DLSS are important to recognize early:

• Trouble standing up after lying down
• Reluctance to jump into the car or onto furniture
• Pain when the lower back is touched
• Limping or weakness in the back legs
• “Root signature” pain: holding a hind limb off the ground
• In advanced cases: loss of muscle mass, dragging toes, or urinary/fecal incontinence

Because these signs can overlap with hip dysplasia, knee injuries, or arthritis, a thorough veterinary exam and advanced imaging (CT or MRI) are often required for a clear diagnosis.

Why It’s Common in Working Dogs

Studies have shown that medium-to-large breed working dogs are at higher risk for DLSS. Their early training, high athletic demands, and repetitive spinal loading make them prone to earlier onset of lumbosacral degeneration.

A review article (Worth et al., 2019, Front Vet Sci) emphasized that DLSS is especially common in working breeds such as German Shepherds and retrievers, yet standardized treatment guidelines are still lacking. This underscores the importance of a case-by-case, multimodal approach.

Treatment Options

First-Line Care

• NSAIDs (anti-inflammatory medications): Reduce pain and inflammation.
• Activity modification and weight management: Reducing jumping and twisting activities can ease pressure on the lower back.
• Rehabilitation therapy: Exercises, underwater treadmill, stretching, and core strengthening are critical for long-term support.

My Predominant Treatment Choice: Epidural Injections

For many dogs, my preferred treatment is a series of three epidural corticosteroid infiltrations. This involves placing a long-acting anti-inflammatory medication directly at the inflamed site under imaging guidance.

A retrospective study in VCOT (2009) treated 38 dogs with epidural methylprednisolone acetate:

• 79% of dogs improved,
• 53% were considered cured,
• Results were comparable to surgery but with much less risk.

This matches my clinical experience: many dogs, including retired working dogs, can avoid surgery with targeted epidural injections, often regaining comfort and mobility for months to years.

Surgery (When needed)

For dogs with severe or progressive neurologic signs (like incontinence), dorsal laminectomy or decompression surgery may be required. Success rates range from 69–95%, but recovery times are longer, and recurrence is still possible.

Emerging Therapies

• Amantadine (oral): A 2025 randomized study in BMC Veterinary Research found that amantadine, —either alone or combined with meloxicam, —produced objective improvements in ground reaction forces in dogs with DLSS, suggesting it can be a valuable part of multimodal therapy (while acknowledging more research is needed).
• Extracorporeal Shockwave Therapy (ESWT): Ongoing studies are exploring ESWT’s role in reducing pain and inflammation in DLSS; early signals are encouraging, and I integrate ESWT selectively alongside core rehab and medical management.
• Regenerative medicine: Platelet-rich plasma (PRP) injections and other biologic therapies are being studied for their potential to support nerve and disc health.

What This Means for Dog Owners

The good news is that DLSS is a treatable condition. With the right diagnosis and management, many dogs can live active, happy lives:

• Family pets often regain mobility and comfort.
• Retired working dogs can enjoy their well-earned rest with less pain.
• Active dogs may return to sport or work in selected cases with careful rehabilitation.

Looking Ahead

DLSS remains a challenge, but veterinary medicine is moving forward. My research team is actively studying lumbosacral disease, and we’re excited about the possibilities.

Stay tuned for more updates as we continue to find better solutions for dogs living with this condition.

If your dog is showing signs of back pain, reluctance to jump, or hind limb weakness, please consult your veterinarian. Early recognition and a multimodal treatment plan can make all the difference.
