Dog Bite Injury: Should You Get a Tetanus Shot?

Dog bite injury

The doctor would like to ask you: Last night, while trying to remove something from my dog's mouth, I accidentally got bitten.
However, the bite did not puncture the skin; it was more like a shallow cut, similar to being grazed by a utility knife, with a small flap of skin lifted but not deep enough to injure the flesh.
I disinfected the area with iodine three times last night.
Should I get a tetanus shot? My dog is vaccinated against rabies and received the vaccine less than a year ago.
All the dogs at home receive regular dental care.
However, I’ve read a lot online and I'm concerned.
My mother says I don’t need the shot.
What should I do?

Gao, 10~19 year old female. Ask Date: 2023/01/26

When it comes to dog bite injuries, it's essential to assess the situation carefully, especially regarding the need for a tetanus shot. In your case, since the injury is superficial and resembles a scratch rather than a deep puncture, the immediate risk of tetanus may be lower. However, there are several factors to consider.

First, let's discuss the nature of the injury. You mentioned that the bite left a small, superficial scratch that did not penetrate deeply into the skin. This type of injury is generally less concerning than a deep puncture wound, which can introduce bacteria more readily into the bloodstream. However, even superficial wounds can become infected, so proper care is crucial.

You have already taken a good first step by cleaning the wound with iodine. Keeping the area clean and monitoring it for signs of infection—such as increased redness, swelling, warmth, or pus—is vital. If you notice any of these symptoms, you should seek medical attention.

Regarding the tetanus shot, the general recommendation is that if you have had a tetanus booster within the last ten years, you may not need another one for a minor injury like yours. However, if it has been more than ten years since your last booster, it is advisable to get one, especially since dog bites can carry a risk of tetanus if the wound becomes infected.
Additionally, since your dog is up to date on its rabies vaccinations, the risk of rabies transmission is minimal. However, if there are any concerns about the dog's health or vaccination status, or if the dog shows any unusual behavior, it would be prudent to consult a veterinarian or your healthcare provider.

Your mother's opinion that you may not need a tetanus shot could be valid, especially if your vaccination history is current. However, it is always best to err on the side of caution when it comes to potential infections and vaccinations. If you are unsure, contacting your healthcare provider for personalized advice based on your medical history and the specifics of the injury is the best course of action.

In summary, while your injury appears to be minor, it is essential to keep it clean and monitor for any signs of infection. If you have not had a tetanus booster in the last ten years, consider getting one. Always consult with a healthcare professional if you have any doubts or if the wound does not heal properly. Taking these precautions will help ensure your health and safety following the dog bite.
