Your Dog Was Just Diagnosed With Degenerative Myelopathy
Here's What That Means
And What You Can Do Starting Today.
If your dog was just diagnosed with DM, you're probably feeling overwhelmed and unsure what to do next.
You're in the right place and you don't have to figure this out alone.
WHY WE ARE SO PASSIONATE ABOUT DEGENERATIVE MYELOPATHY
Tova graced our lives with her gentle spirit and unwavering love.
Nearly two decades ago, Tova was diagnosed with Degenerative Myelopathy, a disease that, at the time, we knew so little about - even as trained veterinarians. Faced with this heartbreaking news, we embarked on a journey driven by our deep desire to help her, seeking knowledge and exploring every avenue of support we could find.
Our search for answers led us to immerse ourselves in research and ultimately sparked a mission that would change our lives and, hopefully, the lives of others. From our experiences with Tova, we developed Canine Rehab On Demand and the at-home rehabilitation programs that we now offer. These programs were born from the love and dedication we had for her, a way to share the knowledge, tools, and hope we discovered with others who might walk a similar path.
Tova’s legacy lives on through this work. Her journey taught us resilience, compassion, and the profound impact that quality of life can have, even in the face of an incurable disease. We wanted to create something meaningful that would make the journey easier for others, so no one would feel as lost or as helpless as we did in those early days.
For everyone who is facing Degenerative Myelopathy with their own cherished companions, know that you are not alone. Tova’s memory lives on in every family we help and every pet whose life we strive to improve. She continues to inspire us to offer the best resources, knowledge, and support so that, through this journey, you and your pet can find strength, hope, and a richer quality of life together.
Tova was more than just a companion; she was our teacher, our guide, and our reason for this mission. We are forever grateful for the gifts she gave us, and we carry her love forward in every life we touch.
We built this program because we wished it had existed when we needed it.
Every exercise, every guide, every video was made for someone who is exactly where we were.

The Clinical Signs Used to Diagnose DM
There’s a greater likelihood of DM if the patient is a high-risk breed and/or between 5 and 14 years of age.
Diagnosis is based on the exclusion of all other disorders, and the genetic test may assist in a diagnosis when used in conjunction with clinical signs to get a presumptive diagnosis. Unfortunately, the only truly accurate diagnosis can be made on post-mortem examination of the spinal cord.
Sudden onset of clinical neurological signs without trauma
No history of pain
Mild ataxia and paresis of the hind limbs without thoracic limbs being affected
Is Your Dog One of These Breeds?
Degenerative Myelopathy has been diagnosed in many different dog breeds, but most of the research has been focused on these breeds:
Boxer, Pembroke Welsh Corgi, German Shepherd, Chesapeake Bay Retriever, Rhodesian Ridgeback, American Eskimo Dog, Bernese Mountain Dog, Borzoi, Cardigan Welsh Corgi, Collie, German Shepherd cross, Golden Retrievers, Great Pyrenees, Kerry Blue Terriers, Nova Scotia Duck Tolling Retriever, Poodle (Miniature), Poodle (Standard), Pug, Shetland Sheepdog, Siberian Huskie
The Five Stages of Degenerative Myelopathy
The Medical Explanation
Degenerative myelopathy, which is also known as chronic degenerative radiculomyelopathy (CDRM), is characterized by clinical signs of slowly progressive hind-limb weakness and paralysis. The symptoms are caused by the oxidative damage to and degeneration of the Schwann cells in the white matter of the spinal cord. This degeneration causes interference with both motor and sensory function of the white matter.
DM is similar to some forms of human amyotrophic lateral sclerosis (ALS), more commonly known as Lou Gehrig’s Disease.
The images to the left show a section of a spinal cord from a dog who had DM (left). The degeneration is seen as a loss of the blue color at the edges (arrows) compared with the spinal cord from a normal dog which is blue throughout (right).

THESE 5 STAGES
Provide good benchmarks for what to expect in your pet with degenerative myelopathy, with possible overlapping of clinical signs.
Stage 1:
Early Stage
Mild signs (Early Stage)
Most common signs and symptoms may resemble those of degenerative joint disease - and be confused with hip dysplasia. These include:
- Weakness in rear legs
- Slight change in gait
- Change in tail position
- Scuffing of rear-paw pads
- Wearing of innermost rear-paw nails
Stage 2:
Early to Mid-stage
First signs of neurological deficits (Early to Mid-stage)
Most common signs include:
- Beginning to have difficulty standing up
- Swaying in the hind end when standing
- Tail movement becomes less active
- Rear legs start to cross each other when walking (worse on turns)
- May start to see urinary and fecal incontinence
- May start to see knuckling when walking, or delayed righting-reflex response times
Stage 3:
Mid-stage
Partial paralysis (Mid-stage)
Most common signs:
- Loss of tail movement
- Jerky movement in the hind limbs when trying to walk
- Inability to walk
- Falling down when walking or standing (“drunken sailor” gait)
- Cross extensor response - when one rear paw is touched, the other rear paw moves
- Asymmetric weakness now progressing to paraplegia
- Easily falls over if lightly pushed
- Wobbling and unable to maintain balance when standing
- Knuckling of the hind paws when standing or trying to walk (very obvious when turning)
- Feet scraping on the ground when walking (constantly)
- First signs of urinary and fecal incontinence
Stage 4:
Late stage
Complete paralysis (Late Stage)
Most common signs:
- Complete paralysis of the hind limbs and loss of all motor and sensory function
- Complete urinary and fecal incontinence
Stage 5:
Final stage
Ascending paralysis to front limbs (Final Stage)
Most common signs:
- Front limb weakness
- Difficulty pulling themselves forward
- Start to see delayed righting-reflex response times
- Knuckling when walking in a supportive device (cart or sling)
- Difficulty breathing as diaphragm is now becoming compromised
Treatment
There’s currently no effective treatment for DM, although there are promising options to slow the progression of the disease. That being said, there are several things we can do to extend the life of a patient by months or even years. If we know early on that a dog is a carrier of or at risk for DM, we can make lifestyle changes so they might never show clinical signs of disease.
These changes include:
◻️ Not allowing the dog to become overweight
◻️ Feeding a diet high in omega-3 fatty acids and low in starches
◻️ Anti-oxidant supplements
◻️ Physical exercise
◻️ Physical therapy
◻️ Rehabilitation modalities
◻️ A patient in stage 3 or 4 may need a supportive device like sling or a cart when hind-limb paralysis is to the point that the dog is unable to stand or walk.

"Ranger was diagnosed at Stage 2. I was devastated and had no idea what to do at home between vet visits. Dr. John's program gave me something concrete to do every single day. By month two I could see Ranger was stronger than he would have been. I don't know how much time we have left together, but I know we're making the most of it. This program gave us that."

The 5 Stages of
Degenerative Myelopathy
__________________________________________________________________
I like to divide DM into five stages. This helps when tracking how the disease is progressing and allows my clients to set objective benchmarks to use in making quality-of-life decisions .
None of the stages is exact, as every patient is different and will progress at a different rate through these five stages. The stages provide good benchmarks for what to expect, but there can be some overlap in terms of clinical signs.
Diagnosing
Degenerative Myelopathy
__________________________________________________________________
When it comes to testing for degenerative myelopathy, candidates are divided into three classes:
At-risk (A/A homozygotes)
Carrier (A/N heterozygous)
Clear (N/N genotype)
I helped develop the two tables below to assist my clients in making breeding decisions to prevent or limit the transition of the SOD1 mutation gene.

Breeds Most Affected by Degenerative Myelopathy
__________________________________________________________________
Canine degenerative myelopathy (DM) has been recognized for over 35 years. It’s a spontaneously occurring, adult-onset, spinal-cord disorder affecting dogs.
Degenerative myelopathy, which is also known as chronic degenerative radiculomyelopathy (CDRM), is characterized by clinical signs of slowly progressive hind-limb weakness and paralysis.
