At a glance the quick version
Sources give about 12-16 lb (roughly 5.4-7 kg); the UK breed page lists 5.67 kg for bucks.
Coat and looks how to spot one
normal fur, medium length; large, powerful body
A big, strong rabbit with a long, flat back, broad shoulders and hindquarters, sturdy legs and tall upright ears. Its coat is soft, dense and of medium length.13
Personality what they are like
A friendly, easygoing rabbit that would rather lounge than race around. Like its Flemish Giant ancestors it is known for being gentle and tolerant, which makes it a pleasant companion for families who have room for a large rabbit.34
Daily activity how busy a day looks
Low to moderate energy. It still needs daily time in a large, safe area to stretch, hop and keep fit.45
Grooming and care the hands-on bits
Regular brushing keeps the dense coat tidy and helps during moults; check nails routinely. Support the whole body when lifting a rabbit this heavy.4
Home where they are happiest
Welfare guidance asks for a combined shelter and exercise area of at least 3 m x 2 m x 1 m high for a pair of medium rabbits, tall enough to stand up on the back legs and long enough to stretch out fully. Breed guides suggest a giant like this needs at least about 20 sq ft (roughly 1.9 m2) of its own, often a shed with a run or a dedicated room.54
Food basics what goes in the bowl
Unlimited hay or grass should form the bulk of the diet, with fresh water always available, plus some leafy greens and a small measured portion of pellets.54
Company who they like around
A sociable animal that should share its home with at least one compatible rabbit, plus regular gentle time with people.5
The story where it all began
British breeders wanted a giant rabbit in more colours than the steel grey allowed for the British Flemish Giant, so they worked with coloured Flemish Giants brought over from America in the late 1940s. Richard Kirk is credited with creating the first British Giants, which were shown at Alexandra Palace in the early 1960s, although some sources date its recognition as a separate breed to the 1940s.213
