A dog bite occurs when a dog uses its teeth to break the skin of a person or another animal. This can happen for various reasons, including fear, aggression, or pain. Dog bites can range from minor scratches to severe injuries, and they may require medical attention depending on the severity. Preventing dog bites involves understanding dog behavior and ensuring proper training and socialization. It's important for dog owners to supervise interactions between their pets and children, as well as to educate others about safe practices around dogs. Vaccination against rabies is also crucial for both dogs and humans.
