Buck is a Saint Bernard
Shepherd dog living the good life. He lives in Santa Clara Valley with his
owner, Judge Miller. He is a domesticated dog until he is stolen and sent to
Alaska where strong sled dogs are in demand. Buck undergoes a series of adventures
where he must shed his pampered doggy past and learn what it means to be wild.
Buck must find his inner-wolf through many trials and tribulations.
Buck - the protagonist,
part Saint Bernard and part Scottish Shepherd. At first, Buck is a pampered dog
living in the Santa Clara Valley in California. As the story progresses, Buck
changes as he is forced to work as a sled dog in the harsh conditions of the
Yukon.
The story's climax occurs
when John Thorton rescues Buck and a true bond is re-established between Buck
and a human. As for a solution or resolution, this occurs when John Thorton is
killed, and Buck no longer has any emotional ties..... he is then free to
return to the wild.
