1, tiger

Pigs are the prey of tigers. Tigers will follow pigs and attack them one by one. This method once completely destroyed the whole herd of pigs. Tigers also chase pigs, but they rarely do this to boars, although it is extremely rare for pigs to kill tigers in self-defense.

2. Wolf

Wolves also eat pigs, especially in Italy, Iberia and Russia. Wolves rarely attack pigs face to face, but often attack the perineum of pigs, causing pigs to lose balance and bleed a lot. In some areas of the former Soviet Union, a pack of wolves can kill 50-80 pigs every year.

Why pigs are natural enemies of snakes;

Pigs evolved from wild boars, which are not only bold but also wild. When they are in the wild, they will eat snakes, even poisonous snakes, and they will not let go when they are hungry. Pig's skin is very thick, much thicker than human's, and its volume is relatively large. Snakes are not easy to bite, so it has little impact on pigs.
