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

Colourswhiteblackdark steel greybluebrown greyopal21

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

Owner questions the things everyone asks

How often should I feed my British Giant?

Unlimited hay or grass should be available every day, along with fresh water. Offer a small measured portion of pellets and some leafy greens daily. For exact amounts, check the food label and ask your vet.456 Furry Diary plan

What should a British Giant eat, and which foods are dangerous?

Hay and grass make up the bulk of the diet, with leafy greens and a small amount of pellets. Avoid muesli mixes, avocado, chocolate, onions, garlic, iceberg lettuce, and other foods listed as toxic. Always provide fresh water.4567

Should I bathe a British Giant?

Bathing is not usually needed as rabbits keep themselves clean. If a bath becomes necessary, ask your exotic-pet vet for safe guidance. Never submerge a rabbit without professional advice.

Does a British Giant need brushing?

Yes, regular brushing keeps the dense coat tidy and helps during moults. Furry Diary's starting plan suggests brushing weekly, and daily while moulting.4 Furry Diary plan

How do I look after a British Giant's nails and teeth?

Check nails every six weeks and trim if needed. Teeth grow continuously, so provide plenty of hay and chew toys; have a vet check teeth weekly. Furry Diary's plan includes nail care every 42 days and weekly teeth checks.4 Furry Diary plan

How much space and exercise does a British Giant need?

A giant rabbit needs at least 20 square feet of its own space, often a shed with a run or a dedicated room. Daily exercise in a large safe area for at least four hours is recommended.45 Furry Diary plan

Should a British Giant live alone or with friends?

British Giants are sociable and should share their home with at least one compatible rabbit. They also enjoy regular gentle time with people.5

How long does a British Giant live?

A British Giant typically lives 4 to 6 years with good care.4

Is a British Giant a good pet for children?

Yes, they are gentle and tolerant, making them pleasant companions for families with enough space. Always supervise young children to ensure safe handling.34

How do I hold a British Giant?

Always support the entire body, especially the hindquarters, when lifting this heavy rabbit. Never lift by the ears or scruff. Ask your vet to show you the safest technique.4
