Degenerative Myelopathy (DM) in dogs typically presents as a progressive, painless, and chronic degeneration of the spinal cord, starting with weakness and loss of coordination in the hind limbs (ataxia). It often begins in older dogs (8+ years) with subtle signs like nail-dragging,knuckling (paw turning under), and swaying, eventually leading to full hind-end paralysis.

What are the first signs of DM in dogs?

Initial signs include loss of coordination (otherwise called ataxia) in the hind limbs; swaying or wobbling when walking; rear feet knuckling over or dragging; and difficulty with walking up steps, squatting to defecate, or getting into the car.

What does DM look like in dogs?

It begins with a loss of coordination (ataxia) or subtle scuffing or "favoring" the back legs. As the disease progresses, dogs will wobble when walking, and may knuckle or drag their back feet. The signs are often noted first in only one back leg but always progress to involve both back legs over time.

What can be mistaken for degenerative myelopathy in dogs?

Peripheral nerve disease, Lumbral Sacral Stenosis, IVDD, "Discospondylitis, Spondylosis, Tick Diseases, Thyroid Problems, Cushings Disease, Wobblers, Polyradiculoneuropathy, Polymyositis, Granulomatous Meningoencephalomyelitis (GME) and spinal tumors are just a few diseases that can initially present similarly to DM.

How do vets test for Degenerative Myelopathy?

Definitive diagnosis requires microscopic analysis of the spinal cord after death. However, veterinarians use clues such as genetic testing, breed, age, and other diagnostics to determine if DM is the most likely cause of your dog's clinical signs.

Degenerative Myelopathy in Dogs - Causes, Signs, Diagnosis and Treatment Options Explained

What are the first signs of myelopathy?

Signs of myelopathy include:

• Pain in the lower back, neck, arm, or leg (though not a cardinal feature)
• Tingling.
• Numbness.
• Weakness.
• Decreased motor skills (difficulty with buttoning shirts, holding silverware, or dropping items)
• Abnormal or increased reflexes.
• Difficulty walking, poor balance.

How quickly does Degenerative Myelopathy progress in dogs?

Degenerative Myelopathy can progress quickly from stage to stage. Significant mobility loss occurs within the first year of diagnosis, in most cases of DM, within six months to 1 year of diagnosis before dogs become paraplegic. Complete organ failure is possible in the end stages of Degenerative Myelopathy.

How to confirm DM in dogs?

Diagnosis. There is no specific test to diagnose DM while a patient is living. Several tests may need to be performed to rule out other potential spinal cord diseases. Testing may include a neurological exam, blood work, X-rays, MRI or CT scan, and spinal fluid analysis.

Do dogs with DM drink more water?

Diabetes mellitus

Excessive water consumption is a prominent clinical sign of diabetes, and finding the water bowl empty more often than usual is often the first sign noticed by dog owners. Other signs of DM in dogs include excessive urination, increased appetite, and weight loss.

Is walking good for dogs with DM?

Yes, dogs with Degenerative Myelopathy should stay as active as possible. Keeping a DM dog active can actually help slow down the progression of the disease. Physical therapy and regular structured exercises, including walking, can help dogs with DM maintain muscle strength and minimize their risk of muscle atrophy.

What is the finger flick test for myelopathy?

Hoffmann's test is a physical exam maneuver that is sensitive but not very specific for cervical myelopathy. There are two methods to perform. The first is to hold and secure the middle phalanx of the long finger and then "flick" the distal phalanx into an extended position.

What can be mistaken for myelopathy?

Among genetic disorders, hereditary spastic paraplegias (HSP) and adrenomyeloneuropathy are perhaps the most obvious mimics. But patients with Friedreich's ataxia can present with a predominant spastic paraparesis, resembling a myelopathy.

What are the 5 stages of degenerative myelopathy?

The Five Stages of Degenerative Myelopathy

• Early Stage (slight signs)
• Early to Mid-stage (neurological deficits noted)
• Mid-stage (partial paralysis)
• Late Stage (complete paralysis)
• Final Stage (ascending paralysis to front limbs)

What can mimic degenerative myelopathy in dogs?

“However, other spinal cord diseases, such as chronic intervertebral disc herniation, and even some tumors, may appear clinically similar. A complete evaluation with diagnostics and performed by a neurologist is recommended to rule out diseases that can mimic degenerative myelopathy.”

How much does a dog DM test cost?

How do I tell if my dog has degenerative myelopathy?

How Do I Know If My Dog Has Degenerative Myelopathy?

1. Swaying backend when your pet is walking.
2. Difficulties rising into a standing position.
3. Scraping nails when walking.
4. Exaggerated movements when walking.
5. Knuckling (rear paws turning under so that your pet walks on their knuckles)
6. Stumbling and tripping.
7. Rear legs crossing.

How to confirm myelopathy?

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.
