Degenerative Myelopathy (DM) in dogs looks like progressive hind leg weakness, incoordination, and eventual paralysis, starting subtly with a wobbly gait, dragging rear paws (knuckling), and difficulty standing, often mistaken for arthritis, and can advance to loss of bladder/bowel control and front limb involvement. Early signs include hind paws "knuckling" (walking on knuckles), swaying hips, scuffing nails, and stumbling, while later stages bring complete 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 a dog?

Degenerative Myelopathy 6 months from initial symptoms.

How do vets test for DM in dogs?

DM is diagnosed presumptively through genetic testing. Blood or a cheek swab is sent to the lab and evaluated for the genetic marker. There are three possible test results: N/N – both copies of the gene are normal, and the dog does not have DM.

How fast does DM in dogs progress?

Unfortunately, DM tends to progress very quickly. Most dogs that have been diagnosed with degenerative myelopathy will become paraplegic within six months to a year.

What causes sudden hind leg weakness in dogs?

Sudden hind-leg paralysis can happen for several reasons, including problems where cushioning material between vertebrae bulges or ruptures, putting pressure on the spinal cord. Blood clots can block blood flow to the legs, causing sudden weakness or paralysis.

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 triggers Degenerative Myelopathy?

DM in most dog breeds is caused by a mutation in the SOD1 gene (SOD1A variant). ​​Dogs with two copies of this variant are considered at a higher risk for developing DM, although it is not guaranteed that they will develop the disease.

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 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.

• Tingling, numbness or weakness.
• Decreased fine motor skills, balance, and coordination.
• Abnormal or increased reflexes in extremities.
• Difficulty walking.
• Loss of bowel or bladder function.

Does prednisone help dogs with degenerative myelopathy?

Can you treat DM? Sadly, as it is a genetic condition, there is no specific treatment for this condition. There is a lack of long-term studies for the treatment of this condition, but it seems that treatment with drugs, such as steroids, do not help to slow the disease.

What breeds of dogs get DM?

Degenerative myelopathy (DM) is characterized by slowly progressive difficulty walking in the pelvic limbs. Degenerative myelopathy occurs predominantly in German shepherd dogs, Corgis and Boxers, but is seen in other breeds, including Rhodesian Ridgebacks, Chesapeake Bay Retrievers, Poodles and others.

How long do dogs have with DM?

How long do dogs live with Degenerative Myelopathy? Dogs generally live with DM for anywhere between six months and three years. Rehab therapy and regular exercise can help improve the quality of life for dogs with DM. Unfortunately, Degenerative Myelopathy has no cure at the moment.

What is a common misdiagnosis for diabetes?

Type 1 diabetes is commonly misdiagnosed in adults, although data on this occurrence is limited. A study from the Diabetes Alliance for Research in England (DARE) found that 38% of type 1 diabetes patients diagnosed over age 30 were misdiagnosed with type 2 diabetes and did not receive the required insulin4.
