Flemish Giant

1 Flemish Giant Breed Overview

Flemish Giant (details)

The Flemish Giant is the largest pet rabbit breed in existence today. It is relatively rare in the domestic market but quite popular abroad. It is not ideal for city dwellers, as it is a big eater with a very large body, making it somewhat troublesome to keep.

The Flemish Giant originated in Belgium and was later developed through planned breeding programs in the United States, which established the breed. Among the largest of all domestic pet rabbits, it has a long history—the breed is generally believed to have been identified by scholars as early as 1860, with the scientific name Flemish Giant. The fact that it is called ‘Giant’ shows just how enormous the Flemish Giant is.

Chinese Name: Flemish Giant

English Name: Flemish Giant

Variety: Flemish Giant. The American Rabbit Breeders Association (ARBA) recognizes 7 color varieties, the most common being sandy brown.

Origin: Belgium

Size standard: Over 13 kg

The Flemish Giant is enormously large, with ears at least 14.6 cm long and a body length of at least 50 cm. The heaviest recorded Flemish Giant weighed 12.7 kg. They are covered in muscle throughout, and their coat is very dense and glossy.

2 Physical Characteristics of the Flemish Giant

Flemish Giant (details)

The Flemish Giant is very large. Usually such giant breeds are raised for meat, but the Flemish Giant is kept as a family pet, making it better suited to farms with plenty of space. It is uncommon in the Chinese market.

The standard weight of the Flemish Giant is 6 kg and can reach up to 13 kg—three to four times the size of a typical pet rabbit weighing under 3 kg, comparable to a three- or four-month-old baby. Beyond its bulk, the Flemish Giant has a pair of large ears and a long, large tail; its ears exceed 5.75 inches and its height reaches about 20 inches, making it an overall impressive breed. The heaviest on historical record weighed an astonishing 28 pounds. They are covered in solid muscle, with an extremely dense coat that is both glossy and silky to the touch. Such a textured appearance has become the living trademark of the giant domestic rabbit.

According to statistics, the standard weight of the Flemish Giant is at least 13 pounds, giving it real heft, and its even coat color is one of the reasons people love it. The ARBA recognizes 7 coat colors, but the most commonly seen Flemish Giant today is still the original sandy-brown line. Although the trend of genetic modification has gradually miniaturized rabbits, with dwarf and mini rabbits now in fashion, do not assume the giant rabbit will disappear into history. Enthusiasts who prefer large rabbits not only actively breed this variety but also promote its size as a defining feature, gradually turning large breeds into giant ones, and the genetics are slowly stabilizing.

3 Flemish Giant Care Tips

The Flemish Giant has underdeveloped sweat glands and dissipates heat mainly through respiration, so prolonged exposure to hot (above 35°C), humid environments can cause mass die-offs. Experiments show the ideal environmental temperature for adult rabbits is 14–20°C, while the nest temperature for newborn kits is 30–32°C; dryness and cleanliness are very beneficial to the Flemish Giant’s health. The Flemish Giant is also quite hygienic, often ‘washing its face’ with its front paws, and keeps eating, defecating, urinating, and sleeping in fixed spots. When a rabbit’s anus, mouth, or nose is not clean, it indicates illness—find the cause quickly and treat accordingly.

4 Flemish Giant Living Environment

The most important environmental requirements for the Flemish Giant are ample space and cleanliness. As a giant breed, it needs more living space than other pet rabbits—not only for basic sleeping but also for exercise.

I. Cage cleaning and disinfection

Litter-trained rabbits usually do not have their whole cage cleaned daily; owners wipe the bottom tray (where the rabbit stands) each day. The tray should be cleaned daily because of droppings, urine stains, and shed fur. Wipe with clean water. If the rabbit uses a litter box, clean the cage base once or twice a week; if not, you may need to do it daily. Likewise, if your usual upkeep is good, disinfect the tray and cage base every 2–4 weeks, depending on your situation. For the cage body itself, periodically rinse with clean water and dry.

II. Cleaning the rabbit litter box

It is recommended to clean the rabbit litter box daily. Normal rabbit droppings are not smelly, but urine has an irritating odor that can irritate the rabbit’s eyes and respiratory tract, so daily emptying is advised. Today there are odor-absorbing wood pellets and paper pellets that work well, but daily emptying is still recommended—not only for hygiene, but also so you can observe the droppings each day. If you do not clean daily, you may lose track of whether the rabbit defecated at all.

III. Precautions when going outside

When the Flemish Giant is young, it is best to avoid taking it outside, because outdoor grass can be dirty and the rabbit can easily fall ill if it eats grass; some lawns are also sprayed with pesticides, and ingestion can be fatal. Free-roaming cats and dogs are another potential danger, so before adulthood keep the rabbit safely at home.

5 Flemish Giant Feeding Guidelines

The Flemish Giant has a huge appetite and, once mature, eats almost continuously throughout the day, so the choice of food and feeding method become very important, as they directly affect the rabbit’s health.

1. Kits aged 30–45 days should be given the rabbit hemorrhagic disease (RHD) monovalent vaccine, 1 ml per kit. Nursing kits need only one feeding per day. Rabbit milk is most abundant at sunrise; as the sun rises, the doe’s milk production drops, so kits should be fed before sunrise.

2. Young rabbits should be fed pelleted feed four times a day (6:00 am, 11:00 am, 4:00 pm, before bed), adding small amounts often and never filling the feeder all at once.

3. Kits under 1 kg (about 2 market catties) must not be fed, or should be fed minimal, green feed; before weaning they should not eat green feed alongside the mother.

4. Nursing does and breeding bucks should be given 10 raw peanuts daily (5 in the morning, 5 in the evening).

5. Do not feed the Flemish Giant only grass without pelleted feed. In pellets, grass meal should make up 35%–50%, with alfalfa meal best, followed by peanut vine, bean pods, sweet potato vine, wild grass, bean stalk, and corn stalk; peanut shell meal is the worst. For peanut vine, cut off the roots, as residual soil on the roots causes diarrhea if eaten.
