The best inference that can be made based on the passage is:
The huskies' typical howl had a frightening sound, but the howl did not mean that anything was wrong.
This inference accurately reflects the travelers' reaction and the description of the huskies' howling as they mistakenly interpreted the sounds as something threatening. The passage suggests that the travelers were frightened by the howls, thinking it was related to a famine, but it was actually just the huskies singing at night.
