ALS causes progressive neurodegeneration, affecting both the central and peripheral nervous systems. The disease leads to advancing weakness and muscle atrophy, and culminates in paralysis and death. DM has been recognized for more than 35 years as a spontaneously occurring, spinal cord disorder in dogs. DM is reported most commonly in German Shepherds but also exists in other breeds, such as Cardigan and Pembroke Welsh Corgis, Rhodesian Ridgebacks, Chesapeake Bay Retrievers and Boxers. There are no treatments for ALS and DM that clearly have been shown to stop or slow progression of the diseases. Owners of dogs with DM usually elect euthanasia six months to a year after diagnosis when the dogs can no longer support their weight with their pelvic limbs, whereas people with ALS typically progress to the state of complete paralysis and succumb to respiratory failure.
