I find that quite un-freakin-believable that a dog can attract ducks, and even more so that long ago, someone in Yarborough, Nova Scotia, saw something in the original progenitor of the breed that they felt should be preserved and bred into dogs that might be used to attracts ducks to their untimely ends.
That is how one invents a dog.
What an idea. Surely their friends and family must have told them they were nuts when they disclosed their plan to create a new dog species. Surely the creators of the great pyramids of Egypt, the Eiffel Tower, or the Suez Canal had to endure the doubts and even scorn of their spouses, families, and brethren for contemplating their crazy notions. There are a million good reasons not to do something, and only a few at the outset to risk it all to do it anyway.
Out of such crazy notions, great things arise. Case in point: modern civilization in all its forms and formats.
Innovation, invention and creation require a certain type of courage - the courage to be wrong. The courage to embrace failure. But it is by that path that success may be found and the world forever changed, in small ways, such as the introduction of a new breed of dog.
