Canine Abscess Study Guide
Overview and Clinical Importance
Abscesses are localized collections of purulent material (pus) resulting from bacterial infection. They represent one of the most common integumentary conditions encountered in canine practice and are frequently featured on the NAVLE.

The resulting pocket of neutrophils, dead tissue, and bacteria creates the characteristic fluctuant or firm swelling associated with this condition.
