Holland Lops can grow to a size of 4.5 lbs. Holland Lops are the smallest breed of lop-eared rabbits and can occasionally weigh under 2 lbs but usually average between 3 and 4 lbs.
Holland Lops were originally bred by a European named Adriann de Cock. He bred Netherland Dwarfs with French Lops and English Lops until the first Holland Lop was born in 1955. This particular rabbit, however, weighed between 4.5 and 6 lbs. and Adriann de Cock continued to experiment with breeding until Holland Lops of 4 lbs. were created in 1964. The Holland Lop Specialty Club was formed in 1970 who specialized in breeding lower weights. Their results now form the current weight standards. In 1975, the breed was introduced to the United States by Aleck Brooks III and the Holland Lop became an official breed, as stated by the American Rabbit Breeders Association, in 1979.
Holland Lops have short, muscled bodies and an apple-shaped head. Their ears are shorter in length than those of Mini or French Lops. Their coloring is categorized into either broken or solid colors and there are seven pattern groups within these categories including self, shaded, ticked, broken, pointed white, wide band and the agouti group which has three or more colors.
