My experience is not fearing dogs leads to not having to fear dogs.
That might sound hyper overly simplistic, but I"m talking about what not fearing dogs does to dogs.
Example: Over a decade ago, my wife and I were out for a walk, when suddenly a rather large dog managed to push open the front door of the house it was in, and charged us with reckless abandon while sporting a determined look of accomplishing harm.
My never having been one to fear dogs suddenly had *me* charging the dog.
And it was fascinating. Soon enough, the dog was attempting to backpedal on pavement. Can you hear the sound of its paws and claws attempting to negate its momentum in order to head back to from where it came, looking and whimpering like a timid puppy anxious for its master to re-open that front door to its safety?
That's exactly what it did.
Three cheers for the absence of fear for them to smell!
