Dog bites are more than just painful—they can lead to serious infections, especially if left untreated. One major concern after a dog bite is tetanus, a potentially life-threatening bacterial infection. But what happens if you don’t get a tetanus shot after a dog bite? Let’s break it down.
What Happens If You Don’t Get a Tetanus Shot After a Dog Bite?
If you don’t get a tetanus shot after a dog bite, the following risks increase:
Infection at the Bite Site
The wound may become red, swollen, warm, and pus-filled.
Delayed healing can lead to serious complications.
Tetanus Symptoms May Develop
Lockjaw (jaw stiffness) is a common early sign.
Painful muscle spasms can spread to the neck and abdomen.
In severe cases, difficulty breathing and swallowing may occur.
Risk of Serious Complications
Untreated tetanus can be fatal.
Muscle contractions can make it impossible to breathe without medical support.
Hospitalization may be required for advanced cases.
How Does Tetanus Relate to Dog Bites?
While tetanus is usually linked to rusty nails and deep wounds, dog bites can also introduce the bacteria if:
✔ The wound is deep or punctured.
✔ The bite area is contaminated with saliva, dirt, or debris.
✔ The person hasn’t had a tetanus booster in over 5 years.
Even if a dog appears healthy, bacteria can enter through the wound and cause serious infections.
When Should You Get a Tetanus Shot After a Dog Bite?
Doctors recommend a tetanus shot after a dog bite if:
✅ You haven’t had a tetanus booster in the last 5 years.
✅ The bite is deep, dirty, or punctured.
✅ There is visible infection or swelling.
If you’re unsure, consult a doctor immediately. Tetanus is preventable, but only if treated in time.
What Else Should You Do After a Dog Bite?
1️⃣ Clean the Wound – Wash thoroughly with soap and water for 5 minutes.
2️⃣ Apply Antibiotic Ointment – Reduce infection risk.
3️⃣ Seek Medical Attention – Get a tetanus shot if needed.
4️⃣ Report the Bite – If the dog isn’t yours, contact animal control to verify its vaccination status.
5️⃣ Consult an Attorney – If the bite caused serious injuries, medical bills, or financial losses, you may have a legal claim.
