Guernsey goats are golden in color, with hues ranging from pale blond to deep bronze. They are registered through the Guernsey Goat Breeders of America, and there is great variety in coat length. The males are sometimes horned but the vast majority are not. Their personalities have been described as "very docile, very friendly". The males have been said to be unusually smelly.
The goat is efficient milking livestock for its relatively small size, producing an average yield of 3.1 kilograms of milk per day; this is less than most Swiss goats, but the milk's high butterfat and protein content (3.72% and 2.81%, respectively)  makes up for the small yield.
The Guernsey Breed is currently under review to be accepted into the American Dairy Goat Association.
