Flemish Giant rabbit

The Flemish Giant is the largest rabbit breed. Show adults must weigh at least 13 lb, there is no upper limit, and ARBA says many pass 20 lb. It is known as docile, but its size makes it a handful to lift and house.

Is the Flemish Giant right for you?

Good fit if

  • You have room for a cage of about 24 × 48 in, or more
  • You want a docile rabbit and can lift 13 lb or more safely
  • You want a large buck to cross onto meat does for faster-growing fryers

Poor fit if

  • The rabbit is for a child to carry and care for alone
  • You only have wire-floored cages with no solid resting area
  • You want the standard meat breed. Penn State ranks medium-weight New Zealand Whites first

Appearance and varieties

Size is the point of the breed. The standard has no maximum weight. Senior bucks, at 8 months and over, must weigh at least 13 lb and senior does at least 14 lb. Even juniors under 6 months must weigh 6½ lb to be shown.

There are seven recognised colours: black, blue, fawn, light gray, sandy, steel gray and white.219

Temperament and handling

ARBA says the breed's docile personality earned it the nickname Gentle Giant. Utah State University Extension makes the same point about large breeds in general: they tend to be more docile than small ones.

The catch is the weight. The same extension service says a Flemish Giant is difficult to hold and handle because of its sheer size, and may not be the best pet for a child. Sit down to handle any rabbit, and have an adult supervise young children.136

Animals vary within a breed. Treat this as what to expect, not a promise, and meet the animal before you buy if you can.

Housing, feed and health

Housing

For a rabbit of 11 lb or more, Utah State University Extension gives a minimum cage of 24 in deep, 36–48 in wide and 18 in high, and adds that bigger is better. The legal minimum ARBA publishes for the breed is 5 sq ft, or 7.5 sq ft for a doe with a litter.

ARBA names Flemish Giants among the breeds prone to sore hocks and says they may need a solid floor, or a resting board in a wire cage.

ARBA gives 55–70°F as the ideal range. Rabbits acclimated to cold cope well with it; they do poorly above 85°F, so give shade and moving air in summer.35

Feed

For a pet rabbit, Utah State University Extension recommends unlimited water, grass hay as about 80% of the diet, leafy greens as about 10%, and small amounts of pellets and treats. Its pellet guide is ¼–½ cup per 6 lb of rabbit.

ARBA's advice for breeders is different: a measured ration of pellets once a day, sized to the breed, with free feeding only for nursing does and growing litters. Change feeds slowly either way.35

Health

ARBA names the Flemish Giant among the breeds prone to sore hocks and says they may need a solid floor or a resting board. Summer heat is a risk: Alabama Extension says rabbits don't cope well above 90°F and in high humidity. Penn State Extension lists cleanliness, good ventilation, close observation and protection from sun and rain as the basics of keeping rabbits healthy.

This is a starting point, not medical advice. If your rabbit stops eating or seems unwell, call a vet who treats rabbits, or your county extension office.51213

Price and where to buy

QualityTypical price
Pet quality$150–$20078
Pedigreed, breeding or show quality$125–$250157

Prices are per rabbit, read from three breeders' pages on 2026-10-08. One breeder prices show stock at $250 and up, so the top of the range is a starting figure; that breeder's page was last updated in April 2017, so its $150 and $250 figures may be out of date. Pedigreed kits at one farm cost less than pet-quality rabbits at another, so compare locally.

History

ARBA says the Flemish Giant is believed to have originated in Flanders, Belgium, and was bred as early as the 16th century. The breed federation's own history is more cautious: it says opinions differ on the real origin, and that the earliest authentic record dates from about 1860, when travellers brought reports of giant rabbits back to England.

English breeders imported them, formed a club and improved the colour and weight. ARBA says the breed was exported to America in the early 1890s to add size to meat rabbits. The federation's history instead ties the first American imports to the time of the Belgian Hare boom, and says the breed drew little notice in America until about 1910.111

Common questions

How big does a full-size Flemish Giant rabbit get?

Show adults must weigh at least 13 lb for bucks and 14 lb for does. There is no maximum, and ARBA says they often weigh more than 20 lb.21

What colours do Flemish Giants come in?

Seven: black, blue, fawn, light gray, sandy, steel gray and white.9

How long do Flemish Giants live?

No lifespan figure here is specific to Flemish Giants. Utah State University Extension says pet rabbits in general live 8 to 14 years, but that is not specific to giant breeds.3

Are Flemish Giant rabbits good for meat?

Partly. Penn State lists the breed as a large meat rabbit but says medium-weight New Zealand Whites are best for meat. Texas A&M suggests using Flemish Giant bucks on New Zealand White does, which gives faster-gaining fryers that reach 4 lb early.1314

Are Flemish Giants good pets?

They are docile, which is where the nickname Gentle Giant comes from. Utah State University Extension warns that their size makes them hard to hold, so they may not suit a child.16

How much space does a Flemish Giant need?

Utah State University Extension gives a minimum cage of 24 in deep, 36–48 in wide and 18 in high for rabbits of 11 lb or more. Use a solid floor or a resting board, because ARBA says the breed is prone to sore hocks.35

How much does a Flemish Giant rabbit cost?

On the three breeder pages we checked, pet-quality rabbits were $150–200, and pedigreed rabbits ran from $125 to $250 and up. One of the three pages was last updated in 2017.7815
