They chatter their teeth when they get a very interesting odor particularly from the pheromones found in the urine of other dogs. There is a organ in the area of the roof of the mouth in the dog that helps decipher sexual pheromones found in urine to let dogs know each other's sexual status and clarify other very interesting smells.
Hope this helps you!
