Canine Degenerative Myelopathy (DM) is a progressive neurologic disease that affects the spinal cord and leads to weakness and loss of coordination, primarily in the hind limbs. As the disease advances, hind limb weakness progresses to paralysis and gradually moves up the spinal cord, eventually affecting the front limbs. In the final stages, DM can interfere with breathing and lead to life-threatening complications.
Degenerative myelopathy is most commonly caused by a genetic mutation and is often compared to ALS (Lou Gehrig’s disease) in humans. While DM is currently incurable, early intervention and supportive care can help slow progression and significantly improve a dog’s quality of life.
Early Signs and Symptoms of Degenerative Myelopathy
Most dogs begin showing signs of degenerative myelopathy after the age of five. Early symptoms are often subtle and may be mistaken for normal aging or arthritis. Common signs include:
- Progressive weakness in the hind limbs
- Difficulty rising or standing
- Stumbling or tripping over the back paws
- Knuckling of the toes
- Scuffing of the hind feet
- Worn nails or inner digits of the rear paws
- Muscle loss in the rear legs, progressing to generalized muscle atrophy
- Tremors in the hind limbs
- Urinary or fecal incontinence
- Front limb weakness as the disease progresses
- Mental anxiety or depression
- Pressure sores over bony areas
- Poor hygiene due to mobility loss
- Increased risk of infections, pneumonia, or sepsis
Note: These symptoms may also indicate other medical conditions. Any changes in mobility or behavior should be discussed with your veterinarian.
Dog Breeds Commonly Affected by DM
Degenerative myelopathy has been identified in more than 40 dog breeds, including:
- German Shepherds
- Boxers
- Golden Retrievers
- Bernese Mountain Dogs
- Shetland Sheepdogs
- Corgis
- Pugs
- Chesapeake Bay Retrievers
Even if your dog is not a breed commonly associated with DM, veterinary evaluation is essential if symptoms are present.
Managing Degenerative Myelopathy in Dogs
Although there is no cure for degenerative myelopathy, the disease itself is not painful. However, loss of mobility can significantly impact daily function and emotional well-being. Developing a physical rehabilitation plan as early as possible is critical. Research shows that dogs receiving consistent rehabilitation often experience improved mobility and a longer lifespan compared to those without therapy.
Physical Therapy and Rehabilitation for DM
When designing a therapy plan for a dog with DM, it is essential to consider the whole dog. Many dogs with degenerative myelopathy also have arthritis or previous orthopedic injuries, such as a repaired cranial cruciate ligament, which must be addressed alongside neurologic decline.
A comprehensive DM rehabilitation plan typically includes:
- Active exercises to maintain strength and mobility
- Passive range-of-motion exercises to preserve joint flexibility
- Massage therapy to improve circulation and reduce muscle tension
- Hydrotherapy, such as underwater treadmill sessions, to allow low-impact movement
- Paw protection to prevent injury from dragging or scuffing
Depending on the dog’s needs, additional therapies such as low-level laser therapy and acupuncture may be recommended. At-home exercise programs are prescribed for every patient, as consistency plays a vital role in slowing disease progression.
Mobility Support and Quality of Life
Supportive tools can greatly improve daily life for dogs with DM. Harnesses such as the Help ‘Em Up Harness assist owners with safe mobility support. As the disease progresses, most dogs will eventually benefit from a dog wheelchair. Wheelchairs allow dogs to remain mobile, explore their environment, and continue engaging in activities they enjoy.
Dogs typically use wheelchairs for a few hours each day, which helps maintain mental stimulation and independence. Regular evaluations are important, including monitoring for urinary tract infections, skin wounds, and pressure sores. In later stages, as weakness progresses forward, breathing difficulties and pneumonia can become concerns. Monitoring emotional health is also essential, as anxiety and depression may develop.
Quality of life should be assessed frequently by considering what your dog enjoys most-whether eating, swimming, playing, walking, or greeting family members. When quality of life declines significantly, euthanasia may eventually become the kindest decision. Until then, focus on comfort, companionship, and meaningful time together.
