Pigs are intelligent animals and can be quite friendly, but they can also be aggressive. If a pig feels threatened, it may attack in order to protect itself. There are several things that can trigger this type of behavior, including unfamiliarity with humans, feeling confined or restricted, and being physically harassed or teased. Pigs may also become aggressive if they are starving or feel like their food is being threatened. In some cases, aggression may be genetic or the result of hormones. Whatever the cause, it's important to be aware of the signs of an impending attack so that you can take steps to avoid getting hurt. These signs include the pig charging toward you, making loud noises, and Pausing with its head down and its tail up. If you see any of these warning signs, it's best to back away slowly and give the pig some space. Pigs are fascinating creatures, but it's important to remember that they can be dangerous if they feel threatened. By understanding their behavior, we can all stay safe around these remarkable animals.
