How does a wolf change its behavior?
When a wolf is hungry, and it desperately needs food to survive,
its behavior will change because it will be getting anxious and
hungry. If it is "breeding season", the wolf will change its
behavior to get a mate. He will attack other wolves to prove he's
the strongest male and so he gets the female. A wolf may change its
behavior if it eats a drug. When a wolf (or any animal) gets a
drug, it may change its behavior in a big way, making the wolf go
crazy or sleepy.
Wolves may change their behavior when they are hurt or weak.
They won't be as strong and they could feel more anxious, knowing
they are hurt.
