What key development in North America provided a humane alternative for exercising the Whippet's innate chasing drive?

Answer

Lure coursing using a mechanized lure

As the breed moved across the Atlantic, sporting practices evolved. Lure coursing became instrumental in supporting the breed's popularity and providing an outlet for their strong innate drive to chase. Unlike the original practice which required setting dogs upon live rabbits, lure coursing involves a mechanized system that pulls an artificial lure across a field. This provided a regulated, humane method for the Whippet to engage in the high-speed, turning pursuit that their physique demanded, aligning their sporting function with changing societal attitudes regarding animal welfare.
