Here's why you should contact a veterinarian immediately:
* Tetanus is a bacterial infection: It's caused by the Clostridium tetani bacteria, which produces a powerful toxin that affects the nervous system.
* Symptoms are severe: Lockjaw is just one symptom. Other symptoms include muscle stiffness, difficulty swallowing, and even seizures.
* Treatment is crucial: Veterinarians administer antitoxin, antibiotics, and other supportive treatments to help your dog fight the infection.
Please do not attempt to treat lockjaw at home. Instead, contact your veterinarian or emergency veterinary clinic immediately.
