Knockglass Billy was one of the fastest, early paced, dogs of his generation. He truly was a sprinter with stamina and class. He won the Red Mills Irish Laurels in 2012 and rattled track records. He has thrown competition class offspring from limited numbers of matings, including Irish Greyhound Derby 2016 favourite, Sonic. Not to mention two finalists in the 2016 Con & Annie Kirby Memorial Stake.
