Idiopathic acute canine polyradiculoneuropathy
Clinically affected dogs are usually previously healthy and present with acute progressive flaccid quadriparesis and hyporeflexia, facial paralysis and laryngeal weakness. These signs often develop 7-14 days after a raccoon bite or scratch, suggesting an underlying an immune-mediated reaction to raccoon saliva or other antigens.
Electrophysiological and pathological features indicated varying degrees of motor-sensory polyneuropathy with some demyelination.
Recovery is usually rapid and often complete in dogs that did not die from respiratory complications.
Supportive intravenous fluids and prednisolone may be required but nursing care is primarily indicated and requires 2 - 4 weeks before recovery of normal ambulation. Relapses may occur.
