No, X-rays cannot directly diagnose Degenerative Myelopathy (DM) because they only show bones, not the spinal cord or soft tissues where DM occurs; however, X-rays are crucial for ruling out other conditions like hip dysplasia or spinal arthritis, with advanced imaging like MRI or CT scans typically needed for definitive diagnosis by exclusion.
A DNA mutation in the SOD1 gene is a major risk factor for Degenerative Myelopathy. A new DNA test identifies dogs as clear, carriers, or genetically at risk. Dogs with two mutated copies of the gene are at higher risk but may not always develop DM.
Peripheral nerve disease, Lumbral Sacral Stenosis, IVDD, "Discospondylitis, Spondylosis, Tick Diseases, Thyroid Problems, Cushings Disease, Wobblers, Polyradiculoneuropathy, Polymyositis, Granulomatous Meningoencephalomyelitis (GME) and spinal tumors are just a few diseases that can initially present similarly to DM.
If you are concerned that your dog may have canine degenerative myelopathy, the following are a few symptoms that can indicate early-stage DM:
There is no specific test to diagnose DM while a patient is living. Several tests may need to be performed to rule out other potential spinal cord diseases. Testing may include a neurological exam, blood work, X-rays, MRI or CT scan, and spinal fluid analysis.

The Five Stages of Degenerative Myelopathy
A myelopathy may also be masked by a second process, such as a polyneuropathy or polyradiculopathy. Lesions outside the cord that give rise to bilaterally symmetrical symptoms and/or signs may be mistaken for a myelopathy.

A blood sample may be taken to rule out metabolic causes of spinal cord dysfunction for example cobalamin deficiency and also for genetic testing for the degenerative myelopathy associated genetic mutation.
Loss of bladder control and fecal incontinence can occur in many canine mobility conditions; IVDD and DM are no exceptions. The main difference between the two conditions is when incontinence issues begin. IVDD incontinence occurs right away when the dog first becomes paralyzed.
Myelopathy is a pinched nerve in the spinal cord that affects the entire spinal cord. It usually develops gradually as the space around the spinal cord (the spinal canal) narrows with age. The narrowing is called spinal stenosis.
How quickly does degenerative myelopathy progress? Unfortunately, DM tends to progress very quickly. Most dogs that have been diagnosed with degenerative myelopathy will become paraplegic within six months to a year.
Pain Level
Arthritis, as we know, is a disease of the joints, and it's very, very painful. Whereas degenerative myelopathy is actually a degeneration of the spinal cord. So it's a neurological disease and it's not actually painful.
Myelopathy Diagnosis
In particular, the 10-second grip-and-release test (10-second test) is used to ascertain the presence of myelopathy hand. This test evaluates the number of repetitive grip–release–grip motion cycles in a 10-second period (over 20 motion cycles is thought to be normal).
Neuromyelitis optica is often misdiagnosed as multiple sclerosis, also known as MS, or is seen as a type of MS . But NMO is a different condition. Neuromyelitis optica can cause blindness, weakness in the legs or arms, and painful spasms.
Myelopathy results from spinal cord compression and can affect the entire spinal cord. Radiculopathy results from compression on an individual nerve root, occurring when a nerve or nerves along the spine become pinched.
Symptoms of degenerative cervical myelopathy
tingling or numbness in the arms or legs (often starting in fingertips or toes) or less commonly in the body. change or loss in the manual coordination or dexterity in the hands (e.g. fastening buttons or tying shoelaces) pain, weakness or heaviness in the arms or legs.
Yes, dogs with Degenerative Myelopathy should stay as active as possible. Keeping a DM dog active can actually help slow down the progression of the disease. Physical therapy and regular structured exercises, including walking, can help dogs with DM maintain muscle strength and minimize their risk of muscle atrophy.
The underlying cause of canine degenerative myelopathy is a genetic mutation. This mutation effectively prevents the dog's body from destroying free radicals when it should, which leads to a destruction of cells.
Red flags for significant neurological compromise include recent trauma, cancer, systemic infection, intractable pain, weakness, gait disturbance, paraparesis, and urinary dysfunction.
The term “spondylotic” refers to one of the possible causes of myelopathy — gradual degeneration of the spine that happens as you age. Therefore, cervical spondylotic myelopathy is more common in people 50 and older.
