degenerative myelopathy in dogs

Degenerative Myelopathy is a condition that affects mostly German Shepherds, but can also be seen in German Shepherd mixed breeds, Siberian Huskies, Corgis and sometimes other breeds. It is generally seen in middle to older aged dogs.

The condition starts with weakness in the hind end. Sometimes dog owners will notice that their dog is occasionally dragging the tops of their back feet on the ground when they walk (knuckling). This weakness, very slowly gets worse over the next year or so. Eventually, it becomes difficult if not impossible for the dog to use his or her back legs. While most dogs can still maintain control of their bladder and bowels, there are some dogs that lose nerve function in these areas too.

There is no specific test that can be used to diagnose this problem. Your vet will likely want to rule out conditions such as intervertebral disc disease (IVDD) and fibrocartilaginous embolism (FCE). However, these two conditions usually cause a sudden change of function in the back end as opposed to the gradual change seen in degenerative myelopathy. Sometimes, another condition such as arthritis of the spine or cancer affecting the spine can look similar to degenerative myelopathy. Your vet will likely want to do some xrays and may possibly refer your dog for an MRI or myelogram.

There is no cure for degenerative myelopathy. The good news is, though, that this is not a painful condition. Many dogs can live quite happily with the weakness, or live with the help of a dog wheelchair. You can also purchase special slings that can be used to help you to assist your dog in getting around.
