The Holland Lop, with a maximum weight of 1.8 kg (4 lb) (as stipulated by ARBA), is one of the smallest lop-eared breeds.

They were first bred by Dutch breeder Adrian de Cock, as a hybrid of the French Lop and the Netherland Dwarf.

[5][6] The history of Holland Lops began with Dutch breeder Adrian de Cock from Tilburg, Netherlands.

Holland Lops were acknowledged by the American Rabbit Breed Association (ARBA) in 1979 and made known to the public in 1980.

[2][4] When Adrian de Cock realized that French Lops were over-sized and Netherland Dwarfs were under-sized in 1949, he decided to breed the two with each other in hopes that their offspring will inherit the optimal size.

At the end of the breeding process in 1955, a Holland Lop weighing less than 3.0 kg (6.6 lb) was born.

11 years after this significant event, de Cock announced Holland Lops weighing less than 2.0 kg (4.4 lb).

In 1964, these rabbits were finally recognized by Dutch breeders and authorities, which led to the introduction of Holland Lops across many countries in Europe.

The result of this breeding process was the Mini Lop, which was acknowledged by the British Rabbit Council in 1994.

[3] In 1976, Holland Lops made their way to the United States, where they were acknowledged by the American Rabbit Breeders Association 3 years later.

[2][3] Similar to most rabbits, Holland Lops' fur is very diverse with a wide variety of colors and combinations.

[9] Albino Holland Lops with white fur and red eyes are not unheard of.

A mutation, very rare among Holland Lops, produces a dark orange color known as ASIP or Agouti Signaling Protein.

Thin, long boned foot structure can cause a change throughout other areas of the rabbit's body, making the head pointier, and the ears longer and thinner.

[11][12] According to the Holland Lop show standards, they are expected to be muscular for their short size.

However, according to ARBA show standards, the Holland Lop at maximum weight is 1.8 kg (4 lb).

Holland Lops, as a breed are considered to be very calm rabbits even though they tend to come off as shy at first.
