This is just another of the amusing facts about dogs that aren't quite accurate. You undoubtedly grew up believing that the old adage "reach out your hand to an unknown dog and let it smell you" was gospel. And it can work, but you must be careful how you go about it. Simply thrusting your hand in front of an unfamiliar dog's face might frighten or alienate her.

And, if you must approach the dog, approach it from the side rather than straight on.

Music is just as good for dogs as it is for humans, and it may even aid with anxiety.
