Final answer:
The relationship between Buck and the other dogs in 'The Call of the Wild' is best described as complex, reflecting a spectrum from confrontational to cooperative dynamics.
Step-by-step explanation:
The word that best describes the relationship between Buck and the other dogs in Jack London's The Call of the Wild is complex. Buck, previously living comfortably in California, finds himself thrust into the harsh world of the Klondike as a sled dog. This new environment forces him to adapt and ultimately brings out his innate animal instincts. The dynamics between Buck and the other dogs he encounters range from confrontational as seen with the snarling and barking at one another, indicative of competition and survival, to cooperative when working together as part of the sled team. Conversely, the last block of text provides a glimpse at a more harmonious relationship where dogs are viewed as beings with mutual respect instead of property.
