What is the sheep's natural enemy?

The sheep's natural enemy is the wolf. Wolves are known to hunt and prey on sheep, posing a significant threat to their population. Sheep have evolved various defense mechanisms, such as flocking together and using their strong herding instincts to protect themselves from potential wolf attacks. Additionally, human intervention through the use of guardian animals, secure enclosures, and other protective measures can help mitigate the risk of predation on sheep by wolves.
