Why does the dog leave man and go back to camp?

Please provide me with the context! I need more information to understand which dog and man you're referring to.

For example, tell me:

* What story or situation are you talking about? Is this from a book, movie, or a real-life event?

* What is the dog's name?

* What is the man's name?

* What is the overall situation? Why did the dog leave the man in the first place?

Once you give me more details, I can help you figure out why the dog went back to camp.
