Dog Bite Injections

Dog bites are not only painful but can also lead to serious infections and diseases if not treated properly. Dog bites can happen suddenly and range from mild scratches to deep wounds. Some may seem harmless, but they can expose you to dangerous infections, especially rabies. Thatâ€™s why knowing about dog bite injections, their timing and protocols is crucial for proper treatment and prevention.

Why Injections Are Needed After a Dog Bite

Dog bites carry a risk of transmitting harmful viruses and bacteria, the most dangerous being the rabies virus, which is almost always fatal once symptoms appear. Injections are essential to:

Prevent rabies infection.
Reduce the risk of tetanus if your vaccine is outdated.
Lower the chance of severe infections from the dogâ€™s saliva or teeth.

How Long Can You Wait After a Dog Bite?

If you get bitten by a dog, itâ€™s best to get treatment as soon as possible. But if you can't see a doctor right away, here's what you should know:

Within 24â€“48 hours: You can still get help and it is likely to be effective.
Beyond 72 hours: The chance of complications increases, especially if you start noticing signs of infection like increased redness, swelling, pain or discharge from the wound.
Never ignore symptoms such as fever, tingling near the wound, neurological signs or any unusual sensations in your body.

What to Do If You Miss a Dose?

Missing a rabies vaccine dose can reduce its effectiveness. Here's what to do:

Contact your doctor immediately: Let them know youâ€™ve missed a dose. They can help you figure out whether to reschedule or start the vaccine process over again.
Do not double: Avoid taking an extra dose on your own, as this is not safe.
Never skip HRIG: If you were given a specific treatment that includes Human Rabies Immune Globulin (HRIG), donâ€™t skip it.

Which Injections Are Given for Dog Bites?

Different types of injections may be given based on the severity of the bite, vaccination history and the dogâ€™s health status.

Anti-Rabies Vaccine (ARV)

This is the main preventive vaccine given in multiple doses. It trains your immune system to fight the rabies virus before it causes harm.

Human Rabies Immunoglobulin (HRIG)

Given in category III bites or if the patient has not received a full rabies vaccine before. It offers immediate, short-term protection.

Tetanus Toxoid

Given if your tetanus vaccination is outdated (more than 5 years) or if the bite is deep, dirty or involves open wounds.

Rabies Vaccine Protocol After a Dog Bite

The standard rabies vaccination schedule includes:

Day 0: First dose, take the first dose as soon as possible after the bite.
Day 3: Second dose.
Day 7: Third dose.
Day 14: Fourth dose.
Day 28: Fifth dose (in some cases).

In severe or category III bites such as deep wounds, bleeding or mucous membrane exposure, Rabies Immunoglobulin (HRIG) is also given on Day 0.

Special Cases and Exceptions

Puppy Bites and Vaccinated Dogs

Even if the dog is vaccinated or itâ€™s a puppy, you should still consult a doctor. Puppies can carry rabies if their vaccination isn't complete.

Children and Pregnant Women

Treatment is safe for both groups and the rabies vaccine poses no risk to pregnancy or fetal development.

Minor Scratch vs Deep Wound

Scratch without bleeding: May require observation and limited vaccination.
Deep wounds or bleeding: Full vaccination and possibly HRIG needed.

What to Do Immediately After a Dog Bite?

Follow these steps before reaching medical care:

Wash the wound thoroughly with soap and running water for 10â€“15 minutes. This helps to remove dirt and bacteria.
Apply an antiseptic like iodine to help prevent infection.
Avoid tying cloth or applying traditional remedies. These can trap germs or make things worse.
Visit a nearby clinic or hospital for a check-up and to determine if you need any vaccinations.

When to See a Doctor?

You should see a doctor immediately if:

The bite is from an unknown or unvaccinated dog.
You were bitten on the face, hands or near joints.
Thereâ€™s bleeding, deep injury or broken skin.
The bite involves a child or an immunocompromised person.
You missed a rabies vaccine dose or developed infection symptoms.
