Understanding Degenerative Myelopathy in Dogs: Causes, Symptoms, and Treatment

Degenerative Myelopathy (DM) is a progressive and incurable neurological disease that affects dogs, particularly in the later stages of their lives. It is a heartbreaking condition that gradually weakens a dog's hind limbs, leading to difficulties in mobility and eventual paralysis. In this article, we will delve into the causes, symptoms, and available treatments for degenerative myelopathy, shedding light on this challenging disease and offering support for affected dog owners.


Causes of Degenerative Myelopathy:

While the exact cause of degenerative myelopathy remains unknown, it is believed to have a genetic basis. Research has identified a mutation in the SOD1 gene as a significant risk factor. However, it is important to note that not all dogs carrying the mutated gene will develop the disease, and not all cases of DM are related to this gene mutation. Other genetic and environmental factors may also play a role, but more research is needed to fully understand the condition's origins.

Symptoms and Progression:

Degenerative Myelopathy typically begins with subtle signs that can easily be overlooked or attributed to other factors. The disease primarily affects the spinal cord, leading to a progressive deterioration of the nerve fibers responsible for transmitting signals between the brain and the hind limbs. Common symptoms include:

Mild hind limb weakness:
Dogs may display an unsteady gait, dragging of the hind paws, or an inability to maintain balance.

Loss of coordination:
Affected dogs may stumble or have difficulty navigating stairs, resulting in frequent falls.

Muscle atrophy:
Over time, the muscles in the hind limbs may shrink due to disuse and lack of nerve stimulation.

As the disease progresses, dogs may experience difficulty controlling their bladder and bowels.

It is important to note that degenerative myelopathy typically does not cause pain or discomfort for the dog, making it even more challenging for owners to detect in its early stages.

Diagnosis and Treatment:

Diagnosing degenerative myelopathy can be a complex process, as it involves ruling out other potential causes of similar symptoms. Veterinarians often rely on a combination of clinical examination, medical history, and specialized tests such as MRI, spinal tap, or genetic testing to confirm the diagnosis.

Unfortunately, there is currently no cure for degenerative myelopathy. However, there are treatment options available to manage the symptoms and provide a better quality of life for affected dogs. These may include:

Physical therapy:
Regular exercise, range-of-motion exercises, and hydrotherapy can help maintain muscle strength and mobility.

Assistive devices:
Mobility aids like carts or harnesses can help dogs with weakened hind limbs to remain active and independent.

Although there are no drugs specifically approved for DM, certain medications, such as non-steroidal anti-inflammatory drugs (NSAIDs) and supplements like vitamin E and omega-3 fatty acids, may be prescribed to manage pain and support overall health.

Palliative care:
As the disease progresses, providing a comfortable and safe environment, as well as attending to the dog's emotional well-being, becomes crucial. Regular veterinary check-ups are essential to monitor the dog's condition and adjust the treatment plan accordingly.


Caring for a Dog with Degenerative Myelopathy:

When faced with the diagnosis of degenerative myelopathy in their beloved pet, dog owners may feel overwhelmed and unsure of how to provide the best care. Here are some practical tips for caring for a dog with degenerative myelopathy:

Modify the living environment:
Create a safe and accessible living space for your dog. Remove any obstacles or hazards that could cause tripping or falling. Consider using ramps to help your dog navigate steps or elevated surfaces.

Provide physical support:
As your dog's hind limb weakness progresses, they may need assistance with walking or standing. You can use a supportive harness or a sling to provide stability and aid mobility.

Maintain a healthy weight:
Obesity can exacerbate the symptoms of degenerative myelopathy and put additional strain on weakened limbs. Ensure your dog maintains a healthy weight through a balanced diet and regular exercise. Consult your veterinarian for guidance on managing their nutritional needs.

Consider mobility aids:
Mobility devices, such as wheelchairs or carts designed for dogs, can greatly enhance your dog's mobility and independence. These devices support their hind limbs, allowing them to continue exploring their surroundings and engaging in activities they enjoy.

Physical therapy and exercise:
Regular physical therapy sessions and targeted exercises can help maintain muscle tone, range of motion, and overall mobility. Consult with a veterinary rehabilitation specialist to develop a customized exercise plan for your dog.

Pay attention to hygiene:
Dogs with degenerative myelopathy may have difficulty controlling their bladder and bowel movements. Establish a routine for regular toileting breaks, and consider using diapers or belly bands to manage any accidents.

Emotional support:
Degenerative myelopathy can be emotionally challenging for both the dog and their owner. Providing comfort, love, and mental stimulation is crucial. Engage in activities that your dog enjoys, such as gentle grooming, puzzle toys, or interactive games that stimulate their mind.

Seek support and information:
Connect with support groups, online forums, or local organizations dedicated to degenerative myelopathy. Sharing experiences and advice with others who are going through similar situations can provide invaluable emotional support and practical tips.

Degenerative myelopathy is a challenging condition that affects the mobility and quality of life of dogs. By implementing modifications to the living environment, providing physical support, maintaining a healthy weight, considering mobility aids, engaging in physical therapy, ensuring proper hygiene, and offering emotional support, dog owners can help their beloved companions live fulfilling lives despite the limitations imposed by the disease.
