A lot goes into greyhound racing, and "heart" is a component you racing enthusiasts talk about. When an athlete digs deep and finds that little bit of an extra gear... that's "heart." Tenacity, a brindle and white female, gives us a great example of "heart" on Sept 3, 2023. Racing for the Blanchard Kennel, Tenacity is owned by C. Cameron and Tracy Wildey. Watch her race from the #7 post position. | National Greyhound Association
