What happens to the dogs during hal and Charles trip to dawson?

During Hal and Charles' trip to Dawson, the dogs suffer greatly due to the harsh conditions and the incompetence of their owners. Hal and Charles overload the sleds and push the dogs beyond their limits, leading to exhaustion and starvation. Ultimately, the dogs are subjected to brutal treatment, which culminates in a tragic outcome as they are unable to withstand the extreme conditions and the neglect of Hal and Charles. This reflects the broader themes of survival and the consequences of human folly in Jack London's "The Call of the Wild."
