The 'Pyrenean Donkey Breeding Stock' is a sub-registry of the Pyrenean donkey. It is unique for Horse Isle, and is intended for donkeys in the game who were born to two Pyrenean parents but don't exhibit the correct mealy pattern.

Breeding rules:
Pyrenean Donkey Breeding Stocks must have either two Pyrenean parents of any subtypes or one Pyrenean parent and one Pyrenean Donkey Breeding Stock. This is because the purpose of the Pyrenean Donkey Breeding Stock is to serve as breeding stock for Pyrenean donkeys and as a registry for Pyrenean donkeys who were born unintentionally with the wrong mealy pattern.

Crossing non-mealy Pyrenean Donkey Breeding Stock with mealy Pyrenean Donkey Breeding Stock will always result in a Pyrenean donkey. However, crossing two non-mealy Pyrenean Donkey Breeding Stock donkeys, or two mealy Pyrenean Donkey Breeding Stock donkeys, will result in a non-Pyrenean donkey.

Conformation:
The conformation of the Pyrenean Donkey Breeding Stock is identical to that of the Pyrenean donkey.
