How does D.M. affect canines?

Degenerative Myelopathy is a gradual and progressive disorder affecting the spinal cord. It usually appears in line with the end of the rib cage causing difficulties in the hind region.

The disease presents most commonly in German Shepherds, so much so that in times gone by it used to be referred to as German Shepherd Myelopathy.  It is now known that DM is found in a range of breeds including Boxers, Golden Retrievers, Rhodesian Ridgebacks, Poodles, Corgis, Pugs and a number of other breeds both pure and mixed.  It can affect both male and female dogs.

DM involves degeneration of the spinal cord affecting signalling and sensing movement. Although it doesn’t typically cause pain, the way a dog develops a way to compensate movement may result in strain on other parts of the body in the shoulders and neck etc. A dog may even still appear bright and animated however DM will affect their quality of life. Types and intensity of exercise have to be closely managed and using stairs can become very hazardous indeed.

Usually DM shows up in dogs around 7 years old or older and typically presents with weakness, reduced coordination in the hind legs (sometimes one leg at a time), a stilted gait, wobbling, dragging toenails or dragging feet (knuckling).

DM is diagnosed by ruling out other conditions (with similar symptoms) first and relatively presumptive because the only direct way would involve the spinal cord under the microscope post mortem.   At least a vet would need to perform a urine test, blood test and imaging. If permitted, spinal fluid collection and analysis can also be conducted.  Once diagnosed, intervention is essential.  Because DM is progressive, if given enough time, will extend further towards the front of the body.
