Considering the second version, where is the conflict or dramatic need going to come from ? it?s wild versus wild, or in other words, a documentary. Dramatic conflict needs an out of the ordinary event that motivates a flawed main character to achieve a goal, however, in this concept you have an animal following its survival instincts during a natural disaster. You would need to anthropomorphize the wolf to make him or her a character and then you?ll require a dramatic need to make the story work. Check out Ice Age as a good example.
