How did you interpret the final four paragrapgh of the story? Did you like this ending? Why or why not?

Buck is free to run...... he can join the pack and live life fully. None-the-less, the last few paragraphs leave an open ending. Will Buck ever feel the need to have a relationship with a human again? We will never know. What we do know is that had Thornton not died, Buck would have stayed loyal to him until he he did. I believe his need to run was great, but his love for John was greater.
