American Goat Society (AGS)
The Nigerian Dwarf is a miniature dairy goat originating from West Africa and developed in the United States. The balanced proportions of the Nigerian Dwarf give it an appearance similar to the larger, Swiss breeds of dairy goats. Shorter height is the primary breed characteristic of the Nigerian Dwarf, with does measuring no more than 22 1/2” at the withers and bucks measuring no more than 23 1/2" at the withers.
They are known for their high-quality milk, often with exceptionally high butterfat content. Nigerian Dwarves are gregarious, friendly, hardy animals that thrive in almost any climate. The medium-length ears are erect and alert. The face is either straight or slightly dished. The coat is of medium length, and straight. The Nigerian Dwarf is the only dairy breed known to occasionally have blue eyes. Both brown and blue-eyed animals are encountered with no preference being given to either eye color. Any pattern, color, or combination of colors is acceptable.
Mature Nigerian Dwarf does should be no more than 22 1/2” tall at the withers. Mature Nigerian Dwarf Bucks should be no more than 23 1/2" tall at the withers.

Nigerian Dwarf does are at least 17 inches tall and may be no taller than 22.5 inches. Bucks are also at least 17 inches tall and no taller than 23.5 inches. While there is no weight requirement, 75 pounds is an average weight.
Many color combinations are common, the ears are of medium length and erect, and the bridge of the nose is either straight or dished. The hair is short and fine.
The Nigerian Dwarf was also developed in the United States and is the only miniature dairy goat breed registered by the American Dairy Goat Association.
Although a small goat, the Nigerian Dwarf doe produces a proportionate quantity of milk with high butterfat.
