How were Perrault, Francois and their team treated when they got to Skaguay? Why did that only last for three days?

In just two weeks they finally make it to Skaguay in Alaska all the way from their earlier location in Canada, averaging forty miles for each day. This accomplishment was a result of Buck's amazing leadership. The dogs rested for three days while Perrault and Francois delivered their important messages from the Canadian government (since Perrault is a courier after all). Then the two men receive new orders from the Canadian government, and with a final hug Francois bids farewell to his beloved Buck.
