For dedicated pet owners and veterinary students, it is essential to be aware of the latest findings on causes, symptoms, diagnosis, and treatment options in order to act early and maintain the quality of life of affected dogs. In this comprehensive article, you will learn everything you need to know about Degenerative myelopathy in dogs, from pathophysiology to current research developments and practical recommendations for prevention and aftercare.

Definition and background of degenerative myelopathy in dogs

The Degenerative myelopathy in dogs This is a chronic, progressive disease of the spinal cord that leads to a gradual deterioration of motor function. This disease primarily affects older dogs, mainly larger breeds such as the German Shepherd, but also other breeds like the Bernese Mountain Dog and the Boxer. Clinically, the disease resembles amyotrophic lateral sclerosis (ALS) in humans and leads to progressive paralysis of the hind limbs over months to years.

Causes and risk factors

The cause of the Degenerative myelopathy in dogs A genetic mutation in the SOD1 gene is assumed to cause a malfunction of the antioxidant enzyme superoxide dismutase 1. This mutation leads to damage to nerve cells in the spinal cord, particularly the motor neurons responsible for controlling the hind legs.

Risk factors include genetic predisposition, advanced age (usually from age 7), and possibly environmental factors that can influence disease progression. The exact pathogenesis is not yet fully understood; however, recent studies indicate a role for immunological processes, such as the involvement of regulatory T cells, which can modulate neuronal degeneration (Wesolowski et al., 2022).

Pathophysiology explained in an easy-to-understand way

The Degenerative myelopathy in dogs The loss of nerve cells in the white matter of the spinal cord leads to disrupted signal transmission between the brain and hind legs. This causes the typical movement disorders, which begin with muscle weakness and coordination problems. Over time, the motor neurons in the forelegs also degenerate, which can lead to complete paralysis.

At the cellular level, the SOD1 mutation leads to misfolding of the enzyme, which promotes the formation of toxic protein aggregates. These aggregates damage the axons of motor neurons and lead to progressive demyelination. Simultaneously, a neuroinflammatory response occurs, activating microglia and astrocytes and releasing pro-inflammatory cytokines that further promote neuronal degeneration.

Recent research suggests that dysregulation of the cellular stress response system and impaired mitochondrial function contribute to the pathophysiological basis of degenerative myelopathy in dogs contribute. The combination of genetic predisposition and environmental factors thus leads to a multifactorial disease pattern with complex molecular mechanisms.

Typical symptoms, course and prognosis

• Early symptoms: Unsteady gait, weakness and ataxia of the hind limbs, frequent stumbling
• Advanced symptoms: Muscle atrophy, incontinence, loss of reflexes in the hind legs
• Final stage: Tetraparesis, complete paralysis, caused by the spread of neuronal degeneration

The course of the degenerative myelopathy in dogs It is a gradual process, usually progressing over several months to years. Unfortunately, the prognosis is unfavorable, as there is currently no cure. However, targeted measures can improve quality of life and slow the progression of the disease.

Degenerative myelopathy in dogs: diagnosis and therapy

Diagnostic procedures

The diagnosis of degenerative myelopathy in dogs is based on a combination of:

1. Medical history: Recording of symptoms and disease progression, especially in older dogs of a suitable breed.
2. Physical and neurological examination: Examination of reflexes, muscle tone and coordination
3. Imaging techniques: Magnetic resonance imaging (MRI) and computed tomography (CT) are used to rule out other causes such as herniated discs or tumors.
4. Laboratory tests: Exclusion of inflammatory or infectious diseases
5. Genetic tests: Detection of the SOD1 mutation to support diagnosis

The Degenerative myelopathy in dogs It is a diagnosis of exclusion, as no specific biomarkers have been established. Differential diagnoses include herniated discs, neoplasms, and infectious myelopathies.
