Pheromones

  If memory serves the good old fashioned Terran dog is still a much loved pet
in Traveller (didn't Arabella Von Erikson get tips on Vargr handling from her
childhood experiences with dogs?).
  Well.... mother nature endowed dogs with a fairly powerful set of pheromones
  now I wonder if Vargr ever suffer problems from being down wind of a Bitch
in Heat?   Even if the Ancients altered the level of pheromone response (which
has never been stated btw) I would doubt they removed it entirely as it is
fundamental to Canine reproduction.
Just a Thought
