The Internet Movie Data Base does not have any reference to a film called "Living with Grizzlies." It does have a film called "Grizzly Man." If this is the film you are referring to you might want to read the story line of the movie.
Yes, Grizzly Man is the movie that I was referring to. As I siad, I did not rent it, just discussed it with the clerk. About a guy who became one with the grizzly.
