Dog Bite First Aid: Wound Care, Tetanus, and Rabies Questions

Dog bites can range from superficial scratches to serious tissue injuries. Even a wound that looks small can introduce bacteria beneath the skin.

Wash minor wounds

Wash the wound thoroughly with soap and water and cover it with a clean bandage. Good wound cleansing is also important when rabies exposure is being considered.

Control serious bleeding

For a deeper wound, apply firm pressure with a clean, dry cloth or dressing. Call 911 if bleeding cannot be controlled or the person becomes faint or weak.

Know when to get medical care

Seek prompt medical attention for deep or serious wounds, loss of function, uncontrolled pain or bleeding, signs of infection, or when the dog's rabies vaccination status is unknown.

Ask about tetanus

Animal bites are considered tetanus-prone wounds because saliva can contaminate the injury. A healthcare professional may recommend a tetanus booster depending on the wound and vaccination history; for dirty or major wounds, CDC guidance uses a 5-year interval for people who completed the primary series.

Ask about rabies risk

If the dog's vaccination status is unknown, the dog is unavailable for observation, or it is sick or behaving abnormally, contact a healthcare provider and local public-health or animal-control authorities promptly. Rabies is preventable when post-exposure care begins before symptoms develop.

A bite wound is not just a skin injury. Infection, tetanus, and rabies risk are part of the decision.
