Canine Pyoderma Study Guide

Overview and Clinical Importance

Pyoderma (literally meaning "pus in the skin") is among the most common dermatologic conditions in dogs and represents one of the primary reasons for antimicrobial prescribing in small animal practice. Understanding pyoderma classification, diagnosis, and treatment is essential for NAVLE success and clinical practice.

The condition is almost always secondary to an underlying disease process, making identification and treatment of primary causes crucial for long-term management.

Etiology and Pathophysiology

Causative Organisms

Staphylococcus pseudintermedius is the predominant pathogen in canine pyoderma, isolated in greater than 90% of cases. This organism is part of the normal canine mucosal flora, colonizing the nares, perineum, and oral mucosa.
