All of Helen's supplies were in a sled, which she pulled, not Charlie! Hid job was to look out for bears. The first bears they met ran away when Helen fired her flare gun but one day they met a bear that was not afraid of the gun. It ran at them.
Charlie grabbed the bear's leg and wouldn't leg go. The bear tried to bite the dog, but Charlie moved out of the way. Eventually the bear ran away. Helen thanked Charlie by letting him sleep in her tent from then on.
Other danger s Helen and Charlie had to face were freezing temperatures and terrible storms. Near the end of their journey, a storm blew away almost all of Helen's supplies. The only things left were a few nuts. When Helen finally reached the North Pole, she was weak from hunger.
When their adventure was over, Charlie went to live with Helen in the United States. Helen never forgot what she owed the dog. 'What charlie wants', she said, 'Charlie gets!'
