Canine Bite Wounds: Triage, Lavage, Closure

3,314 words 11 min read 2 figures Reviewed November 6, 2026

Bite wounds are among the commonest reasons dogs need emergency care. Their defining feature is that the skin hides the damage: a dog's teeth puncture, then grip, crush and shake, so a pair of tiny holes can sit over torn muscle, a large pocket of dead skin and, over the chest or neck, injured airways, ribs and lungs. Management therefore runs in a fixed order: stabilize, find the hidden injuries, clean and debride, then decide on closure and antimicrobials.

Key facts

Bite wound at a glance
  • Species and system: dogs (and cats bitten by dogs); skin and soft tissue, but deep injuries can involve the thorax, neck airway and abdomen.
  • Cause: penetrating, crushing and shearing trauma from teeth, with contamination by oral and skin bacteria.
  • Who is at risk: small dogs (10 kg or less) are bitten most and are more likely to have multiple injuries; deaths occur almost only with thoracic or abdominal wounds.
  • Classic presentation: small punctures and bruising, sometimes with subcutaneous emphysema, dyspnea or shock out of proportion to the visible wound.
  • Wound status: always contaminated; closure is usually delayed or the wound is managed open.
  • Zoonotic or reportable: the wound itself is not, but every bite raises the question of rabies exposure, and dog saliva can carry Capnocytophaga canimorsus, which causes severe infection in at-risk people.
