He related how one of his lead dogs on one of his surveying expeditions (he was the leader of the British Antarctic Survey at Stonington in the 50s) once refused to accept a command to turn left while pulling his sledge. He insisted, and the dog went a few feet then stopped dead at the place where the land stopped and led to a gap filled with water. The dog looked back at him as if to say, "I told you so." He then commanded the dog to go to the right and cross a hill, and, without being told, the dog then did that and turned back around to the left afterwards to continue where the correct path had been. Fuchs had never been to this particular place before, but the dog had. This was an example that he used to demonstrate the intelligence of these dogs, and the value that they gave to the expeditions in this area. Especially in the days when airplanes were scarce.
Fuchs also mentioned how well the men got to know the dogs during these expeditions. They could distinguish the dogs' individual voices and behaviors to the point that they could tell when a row started outside their tents exactly which dog had started it and which others were involved.
