Several conditions can mimic canine Degenerative Myelopathy (DM), which is a progressive, painless, and fatal spinal cord disease. The most common mimics are Intervertebral Disc Disease (IVDD), degenerative lumbosacral stenosis, spinal tumors/cysts, hip dysplasia, and arthritis. These, unlike DM, often cause pain.

What mimics DM in dogs?

Differential Diagnosis

14 Disorders that often mimic and coexist with DM include degenerative lumbosacral syndrome, intervertebral disc disease, spinal cord neoplasia and degenerative joint diseases such as hip dysplasia or cranial cruciate ligament rupture.

What looks like degenerative myelopathy in dogs?

The affected dog will wobble when walking, knuckle over or drag the feet. This can first occur in one hind limb and then affect the other. As the disease progresses, the limbs become weak and the dog begins to buckle and has difficulty standing. The weakness gets progressively worse until the dog is unable to walk.

How to rule out DM in dogs?

Diagnosis. 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.

How to confirm diabetes mellitus in dogs?

Diagnosis. Your veterinarian will evaluate clinical signs in combination with blood work and a urinalysis to diagnose diabetes. Additional tests may be needed to help rule out any coexisting conditions such as pancreatitis. Stress can cause temporary increases in blood sugar.

Degenerative Myelopathy in Dogs - Causes, Signs, Diagnosis and Treatment Options Explained

How to tell the difference between hip dysplasia and degenerative myelopathy?

DM is a non-painful condition, whereas osteoarthritis and hip dysplasia are uncomfortable. Additionally, a dog with DM will have proprioceptive deficits, meaning they cannot tell if their paws are positioned correctly when placed upside down.

What can be mistaken for myelopathy?

Among genetic disorders, hereditary spastic paraplegias (HSP) and adrenomyeloneuropathy are perhaps the most obvious mimics. But patients with Friedreich's ataxia can present with a predominant spastic paraparesis, resembling a myelopathy.

Can degenerative myelopathy be misdiagnosed?

Degenerative Myelopathy is a progressive, adult-onset spinal cord disease that causes weakness in the hind limbs and eventually leads to paralysis. Because its symptoms mimic other spinal conditions, DM is often misdiagnosed.

What causes sudden neurological issues in a dog?

Causes may include genetics, unknown origins (idiopathic epilepsy) brain injury, brain tumors, strokes, infections, or metabolic issues.

What is a common misdiagnosis for diabetes?

Type 1 diabetes is commonly misdiagnosed in adults, although data on this occurrence is limited. A study from the Diabetes Alliance for Research in England (DARE) found that 38% of type 1 diabetes patients diagnosed over age 30 were misdiagnosed with type 2 diabetes and did not receive the required insulin4.

Can pancreatitis be mistaken for diabetes in dogs?

Diabetes mellitus and pancreatitis are two distinct diseases encountered commonly in small animal practice. Whilst the clinical signs of diabetes mellitus are usually unmistakeable, a firm diagnosis of pancreatitis can prove more elusive, as clinical signs are often variable.

Can you reverse diabetes in dogs without insulin?

While insulin injections remain the cornerstone of diabetes treatment in pets, alternatives such as dietary management, oral medications, weight control, and supplements may play a supportive role in specific cases. However, these approaches are rarely sufficient on their own and require close veterinary supervision.

What disease mimics diabetes in dogs?

Hyperadrenocorticism is a slowly progressive disease with signs that vary in severity depending on the duration and degree of cortisol excess. Clinical signs are similar to diabetes mellitus: Polyuria. Polydipsia.

What are the differentials for degenerative myelopathy in dogs?

Differential Diagnoses

Differentials for DM include other non-painful, slowly progressive T3-S2 spinal cord diseases including: Chronic intervertebral disc protrusions (Hansen type II) Degenerative lumbosacral stenosis. Other degenerative causes of spinal canal stenosis (joint and ligament hypertrophy)

Does prednisone help dogs with degenerative myelopathy?

Can you treat DM? Sadly, as it is a genetic condition, there is no specific treatment for this condition. There is a lack of long-term studies for the treatment of this condition, but it seems that treatment with drugs, such as steroids, do not help to slow the disease.

How to rule out myelopathy?

Myelopathy Diagnosis

1. An X-ray to rule out other problems.
2. An MRI scan for a detailed look of the spine and spinal canal, which can show areas of stenosis.
3. Myelography uses a contrast material and a real-time form of an X-ray called fluoroscopy to reveal abnormalities of the spinal cord.

How do vets test for degenerative myelopathy?

Definitive diagnosis requires microscopic analysis of the spinal cord after death. However, veterinarians use clues such as genetic testing, breed, age, and other diagnostics to determine if DM is the most likely cause of your dog's clinical signs.

Can DM in dogs come on suddenly?

No, Degenerative Myelopathy (DM) in dogs typically does not come on suddenly. Instead, it usually manifests gradually over time. The early signs of DM are often subtle and may be overlooked or mistaken for normal aging. Initially, dog owners may notice mild changes in their dog's gait or hind limb coordination.

What can be mistaken for degenerative myelopathy in dogs?

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.

How to tell the difference between IVDD and DM?

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.

Can a dog have degenerative myelopathy without the gene?

Breeding two carriers of the SOD1 allele together is predicted to produce 25% pups that may develop DM. It is important to note that similar disease presentation has been observed in animals that do not have the SOD1 allele and not all dogs that are DM/DM will develop signs of disease.

What are the alternatives to putting down a dog with DM?

While I typically recommend treatment alternatives such as pet hospice, acupuncture, or physical therapy, these won't prolong your pet's life. However, these can make your dog's life much more comfortable within the six months to two years of diagnosis.
