Managing subcutaneous abscesses in dogs — from bite wound origins to treatment and prevention.
Subcutaneous abscesses cause significant localised pain and welfare impairment. The pressure of accumulating pus within a tightly bounded space causes intense, constant discomfort. Affected areas are exquisitely tender on palpation — dogs react strongly when the abscess is touched and may become aggressive from pain. The heat, swelling, and pain of an active abscess impairs normal activity and rest.
Untreated abscesses progress through three welfare phases: accumulation (increasing pain from pressure), rupture (relief but open wound), and either healing or complication (secondary infection, sinus tract formation). The spontaneous rupture provides temporary relief but leaves an open wound that requires management. Bite wound abscesses may have multiple tracts and cavities that delay healing.
Treatment requires establishing drainage — surgically opening the abscess under sedation, flushing the cavity thoroughly, and maintaining drainage until the cavity has healed from within. Appropriate systemic antibiotics reduce the bacterial load and prevent local spread. Pain management throughout is essential for welfare.
