Degenerative Myelopathy in German Shepherds

Clinical overview

Why German Shepherds carry elevated Degenerative Myelopathy risk

Degenerative myelopathy (DM) is an SOD1-associated neurodegenerative disease disproportionately seen in German Shepherds. It mimics chronic disc disease but is typically non-painful and relentlessly progressive. Genetic test results, serial neurologic exams, and assistive-device timelines help families plan quality-of-life decisions and distinguish DM from compressive myelopathy.

Watch list

Symptom checklist

• Slowly progressive rear-limb ataxia without obvious pain
• Knuckling or scuffing of toenails on the hind feet
• Crossing over of pelvic limbs when walking
• Eventual paraparesis progressing toward thoracic limbs
• SOD1 mutation carrier / at-risk genetic status on record

Digital vault protocol

Emergency & longitudinal management

1. Archive SOD1 genotype reports and counseling notes
2. Perform and date serial neurologic exams (proprioception, withdrawal, urinary status)
3. Log physiotherapy, hydrotherapy, and harness / cart introduction dates
4. Rule-out imaging (MRI) summaries should live beside the DM working diagnosis
5. Maintain a quality-of-life scorecard shared with all caregivers
