How did buck get to seattle in the call of the wild?

In "The Call of the Wild," Buck is taken to Seattle after being kidnapped from his home in California by Manuel, a gardener who needs money to pay off his gambling debts. Manuel sells Buck to dog traders, who then transport him north to the Klondike region during the gold rush. The journey involves being shipped on a train and then loaded onto a boat, ultimately leading to his arrival in Seattle, where he is sold to a series of harsh owners before being thrust into the brutal life of a sled dog.
