Degenerative Myelopathy is a disease in which there is a gradual loss of coordination and strength that begins in the hind quarters. Dog breeds prone to this are the Cardigan Welsh Corgi and the Pembroke Welsh Corgi. This disease afflicts older dogs, from 8 years old onward, and is not painful.
Symptoms
A dog with Degenerative Myelopathy will wobble when walking, knuckle over or drag the feet. The disease may first affect one hind leg and then both. As the disease progresses, the dog will no longer be able to stand. Loss of urinary and fecal continence may also occur. These symptoms are similar to the symptoms of some other diseases, such as herniated intervertebral disks, and these must be ruled out before a diagnosis of Degenerative Myelopathy is made.
Treatment
There are currently no cures for this disease. Dogs suffering from it can be helped by good nursing care, physical rehabilitation, pressure sore prevention and monitoring for urinary infections. Harnesses and carts can help the dogs walk.
