Weanling: A foal no longer nursing and not running alongside its mother, typically four months to a year old, used for both horses and donkeys.
Gelding: A castrated male horse or donkey.

This terminology can be confusing for newcomers. Some terms are universally used, while others are region-specific or shared with horses. In the US, remember that an intact male donkey is a "jack," a female donkey is a "jenny" or "jennet," and a castrated male donkey is a "gelding." A "weanling" is under a year old and no longer dependent on its mother, while a "yearling" is between one and two years old.
In the US, terms like "stallion," "mare," and "filly" are primarily used to describe horses. However, "gelding" can refer to both castrated horses and donkeys.
Color terminology also differs. In the US, spotted donkeys are simply called "spotted," rather than "paint," "pinto," or "Appaloosa." The recognized colors for donkeys in the US are spotted, black, red, brown, gray, dun, gray dun, white, frosted spotted white (FSW), and ivory.
Solid-colored donkeys can be further described based on the presence or absence of light markings. "WLP" indicates light points, such as eye rings, muzzle, belly, and inner thigh markings, while "NLP" denotes the absence of these markings.
FSW donkeys have white coats with black pigment around their eyes and skin. They should not be confused with ivory donkeys, which have cream-colored coats and blue eyes.
