Did you know that a female donkey is called a Jenny? And if you're a female donkey in certain parts of the world (western Canada, for example) people might even call you a Jennet. The word Jennet takes root in the Spanish language (sometimes spelled "genet") and dates back to the Middle Ages, when people used the word to refer to a small horse.
Male donkeys have two nick names: Jack and John. A Jack refers to an in-tact male donkey that is able to breed, while a John is a castrated male donkey that is unable to breed.
