# Aller Breeders

Breeders minted from 1643 to 1760

**Breeding Re-Roll:** Breeders minted between 1643 to 1760 provide the ability to re-roll a Breeding session. When you open either a Greyhound Racer or Whippet pack and have a Breeding Re-Roll breeder in your kennel you will have the option to accept the original hound or re-roll and try again for a better outcome. All Aller Breeders have been minted and may be available on the secondary market.
