Degenerative myelopathy (DM) in dogs is a progressive neurological disease characterized by five stages, starting with mild hind-limb weakness and progressing to full paralysis, usually over 6–12 months. The stages transition from early gait abnormalities to complete, non-ambulatory paralysis, ending in severe dysfunction, including potential breathing difficulties.

What is the timeline for degenerative myelopathy?

Lifespan of Dogs with Degenerative Myelopathy

The speed of progression of symptoms can vary, but from the start of signs to the point of incontinence or inability to walk is typically 6-18 months. This is when most owners would make the call to euthanise.

What is the final stage of myelopathy?

Stage 4: Final stages of degenerative myelopathy

The final stage, stage 4, may occur approximately 24 to 36 months after diagnosis. By this stage, the dog is completely paralyzed with loss of all spinal reflexes. They usually have severe muscle loss over their whole body as well.

Does DM cause shaking in dogs?

DM is a progressive spinal disease that slowly weakens a dog's limbs that is common in older German Shepherds. As a dog's spine slowly degenerates, the lack of nerve signals to the muscles in the hind legs can cause muscle spasms, involuntary muscle contractions, as well as shaking in the back legs and feet.

How is myelopathy diagnosed?

1. Imaging tests, like a spine X-ray, MRI or CT scan.
2. Myelogram, using contrast dye, along with imaging tests to show the relationship between bones and soft tissue in your spine.
3. Nerve function tests, such as electromyography or evoked potentials, to measure how your brain and body send messages.
