What is Wobbler’s Disease?

Wobbler’s disease is a term used to describe two different conditions that cause spinal cord compression in the neck of dogs. Both can produce similar signs, but they arise from different causes and require different treatment strategies. Getting the diagnosis right is the critical first step.

The two forms

One form is seen in younger, large breed dogs — most often Great Danes and Mastiffs. The medical name for this is Caudal Cervical Spondylomyelopathy, or CCSM. In these dogs, abnormal bony development causes the walls of the vertebral canal to thicken and narrow, compressing the spinal cord from the sides, typically toward the base of the neck. Because this is a developmental problem, signs tend to appear as the dog is still growing or shortly after reaching adulthood.

The other form is more common in older dogs, particularly Doberman Pinschers. This version is called Disc Associated Wobbler’s Syndrome, or DAWS. Here, years of degenerative changes cause intervertebral discs to bulge and surrounding ligaments to thicken, creating a different kind of compression — one that worsens gradually as the discs continue to break down.

What does it look like?

In both forms, the hallmark sign is an unsteady, wobbly gait in the rear limbs — which is where the disease gets its common name. Dogs may appear to sway, stumble, or have difficulty placing their feet correctly. Neck pain or stiffness is also common. Some dogs hold their head low or resist looking up. Weakness can progress to the point where a dog struggles to rise from lying down or has trouble navigating stairs.

Because the forelimb and hindlimb nerve pathways are affected differently depending on the level of compression, some dogs develop a distinctive pattern where the front legs take short, choppy steps while the rear legs take long, sweeping strides — sometimes described as a “two-engine gait.”

How is it diagnosed?

Because the two forms can look identical on a basic exam, imaging is essential. X-rays can suggest the presence of disease but cannot show the spinal cord itself. MRI is the best tool for distinguishing between CCSM and DAWS, pinpointing the exact location and nature of compression, and guiding treatment decisions.

What are the treatment options?

Both forms can be managed medically or surgically. Medications — typically low-dose corticosteroids — can help control clinical signs and reduce inflammation. But medication does not stop the underlying disease from progressing, and most patients will worsen over time without definitive treatment.

Surgery for CCSM focuses on removing the compressive bony tissue and relieving pressure on the spinal cord. For DAWS, surgical options aim to decompress the affected disc spaces, though these cases carry a well-known risk called the “domino effect” — where adjacent disc levels develop problems after the first is treated. Understanding this risk is part of careful surgical planning and patient selection.

If you are seeing signs

A neurologic evaluation is the right first step. Early diagnosis gives more options and often leads to better outcomes. If your large breed dog is moving differently, seeming painful, or showing any change in coordination, do not write it off as normal aging.
