Introduction

  • Cause: skin microtrauma or prolonged water immersion + Pseudomonas aeruginosa-contaminated water ± individual susceptibility especially in medium-large breed with medium-long hair coats.
  • Signs: pain, malaise, exercise intolerance, regional rash.
  • Diagnosis: clinical history and appearance with consistent cytology and bacterial culture (± histopathology).
  • Treatment:
    • Mild-moderate: initial cleansing, topical and systemic antimicrobials, plus analgesia.
    • Severe: hospitalization and intensive treatment.
  • Prognosis: good in most cases, but fatal sepsis has been reported and permanent scarring can occur.
