What to Do if a Dog Bites: First Aid, Rabies Prevention & Vaccine Guide

A dog bite should always be taken seriously. Even a small bite or scratch can introduce bacteria or, in rare cases, expose a person to rabies. Knowing what to do if a dog bites can help reduce the risk of infection and ensure you receive the right medical care as quickly as possible.

Whether the bite comes from a pet or a stray dog, prompt wound care and medical evaluation are essential.

Immediate First Aid After a Dog Bite

If you or someone you know has been bitten by a dog, follow these important steps immediately:

• Wash the wound thoroughly with soap and running water for at least 15 minutes.
• Apply gentle pressure if the wound is bleeding.
• Cover the wound with a clean, sterile dressing.
• Seek medical attention immediately, especially if the bite is deep, on the face or hands, or caused by an unknown or unvaccinated animal.
• Do not delay treatment, even if the wound appears minor.

Early medical care greatly reduces the risk of serious complications.

Can a Dog Bite Cause Rabies?

Rabies is a viral disease that affects the brain and nervous system. It is usually transmitted through the saliva of an infected animal.

Although not every dog bite results in rabies exposure, any bite from an unknown, stray, sick, or unvaccinated animal should be evaluated by a healthcare professional immediately.

Once rabies symptoms appear, the disease is almost always fatal. Fortunately, rabies can usually be prevented with prompt post-exposure treatment before symptoms develop.

Signs of Infection After a Dog Bite

Even if rabies is not a concern, dog bites can become infected.

Watch for these warning signs:

• Increasing redness around the wound
• Swelling
• Warmth or tenderness
• Pus or unusual discharge
• Fever or chills
• Increasing pain
• Red streaks extending from the wound

If any of these symptoms develop, seek medical care as soon as possible.

Rabies Vaccine After a Dog Bite

A healthcare professional will determine whether you need rabies post-exposure prophylaxis (PEP) based on:

• The type of animal involved
• Whether the animal can be observed or tested
• The animal's vaccination status
• The severity and location of the bite
• Local rabies risk

If recommended, it is important to start treatment as soon as possible and complete the full vaccine schedule exactly as prescribed.

Some people may also require Rabies Immunoglobulin (RIG), depending on the nature of the exposure and their vaccination history.

When Should You See a Doctor?

Seek medical care immediately if:

• The bite breaks the skin.
• The wound is deep or heavily bleeding.
• The bite is on the face, hands, feet, or near joints.
• The animal is unknown, stray, or behaving unusually.
• The dog's rabies vaccination status is unknown.
• You have diabetes, a weakened immune system, or poor circulation.
• Signs of infection develop.

How to Prevent Dog Bites

Simple precautions can help reduce the risk of dog bites:

• Never approach unfamiliar dogs.
• Teach children how to interact safely with animals.
• Avoid disturbing dogs while they are eating, sleeping, or caring for puppies.
• Keep your own pets vaccinated against rabies.
• Supervise young children around pets at all times.
