# Zab Judah Breeders

**Training Re-Roll:** Breeders minted between 1501 to 1642 are dedicated to the 6 x Boxing world champion Zab Judah and can be identified with a Zab Judah collar as per the image below. If you hold one of these Breeders in your kennel every hound with a training session available is entitled to re-roll a single training session. [See Training Re-Roll for more information.](/muzzle-run-docs/muzzle-run-racing/training/training-re-rolls.md) All Zab Judah Breeders have been minted.
