Contributor(s): Kyle Braund

Introduction

  • Cause: believed to be inherited as an autosomal recessive trait seen in young long-haired Dachshunds 6-8 months of age.
  • Signs: ataxia, conscious proprioception deficits, absent pain perception.
  • Weakness and muscle atrophy not features.
  • Urine dribbling and vomiting may be seen.
  • Self-mutilation of penis.
  • Diagnosis: age, breed, clinical signs, sensory nerve biopsy.
  • Treatment: no treatment available, apart from use of a muzzle to prevent self-mutilation.
  • Prognosis: favorable.

Pathogenesis

Predisposing factors

  • Undetermined.
