Steroid-Responsive Meningitis-Arteritis in Dogs

Understanding SRMA — a painful immune-mediated neurological disease affecting young dogs.

Key Facts

Welfare Considerations

SRMA causes severe acute welfare impairment. The cervical pain experienced is extreme — affected dogs cry when touched, refuse to lower their heads, adopt a hunched posture, and resist any neck movement. The pain is so severe that dogs may refuse to eat, drink, or move voluntarily. Combined with high fever, the systemic effects of active SRMA cause significant suffering.

The diagnosis can sometimes be delayed because the presentation mimics other painful conditions. Every day without appropriate treatment prolongs unnecessary suffering. Cerebrospinal fluid analysis confirming elevated protein and white cell counts is the diagnostic gold standard and should be performed promptly when SRMA is suspected.

Response to prednisolone is typically dramatic — most dogs show marked improvement within 24-48 hours of starting appropriate doses. Long-term management requires careful dose tapering over 6-12 months to prevent relapse. CSF rechecks guide dose reduction. Relapse is managed by returning to full immunosuppressive doses with slower subsequent tapering.
