The Holland Lop rabbit is a Dutch breed initially developed by rabbit breeder xxxx. Holland Lops are the result of breeding a larger French Lop rabbit with a smaller Netherland Dwarf rabbit. The standards of perfection for the breed were adopted in Europe in 1964. The Holland Lop was officially recognized in the United States as a pure breed by the American Rabbit Breeders Association (ARBA) in 1979. The typical Holland Lop life span is 7–10 years, and they reach a maximum weight of 4 pounds. Full-grown Holland Lops have a compact yet muscular body with heavy bones. The ARBA recognizes over 30 different coat color and pattern variations. Ideally, this rabbit has a large head, short and rounded nose, and characteristic floppy ears that fall close to the face.
