Donkey

Donkeys are a recurring race in the Legend of Zelda series, appearing in both The Legend of Zelda: Majora's Mask and The Legend of Zelda: Breath of the Wild. They are smaller and stockier than horses with shorter manes.

Majora's Mask
A donkey is used by Cremia to pull her milk wagon. If Link helps Romani repel Them on The First Night he can help Cremia deliver her milk the following morning, protecting the cart and donkey from the Gorman Brothers who seek to destroy her cargo.

Breath of the Wild
According to the Hyrule Compendium donkeys are raised as livestock in the countryside, as a result they don't exist in the wild. Donkeys can be found in stables throughout Hyrule, they also frequently accompany merchants who favour them over horses due to their greater strength.
