Tetanus is a bacterial infection caused by Clostridium tetani bacteria. While tetanus can be transmitted through a wound, it is not commonly transmitted through a dog bite.

However, if the dog bite is deep, contaminated with soil or feces, or if the wound is left untreated and becomes infected, then it can create an environment where tetanus bacteria can thrive. In such cases, it is possible to contract tetanus from a dog bite.

Therefore, it is important to properly clean and treat any dog bite wounds, and seek medical attention if there are any signs of infection or if you have not had a tetanus vaccine in the past 10 years.
