Spielberg (by Sunny-Boy) entered Dutch breeding with a bang. In his first breeding year (2007) he immediately received more than 500 mares. And that without a KWPN breeding license. He was never approved at the KWPN, but the people around Spielberg are still happy with it. "And I also believe in the people who have a Spielberg".
