The Flemish Giant is also called the "king of rabbits" because of their large size, longevity, and personality. These giant rabbits can reach an immense size very quickly. Flemish Giants can weigh as much as 4 pounds or more by 7 or 8 weeks of age. A Flemish rabbit is a sweet, lovable companion who can be kept inside and blends well into family life.

Flemish Giant Characteristics

Flemish Giant rabbits have a distinctive look, and it's not just their size that makes them stand out among other bunnies.

Physical Description of a Flemish Giant Bunny

According to the American Rabbit Breeders Association (ARBA), there is no maximum weight for a Flemish Giant. The breed is a semi-arch variety of rabbit, which means that the arch in the animal's back starts at the base of the shoulders and curves up and over toward the tail. Other breed standards include:

  • Body - Long, lean and powerful body
  • Head - Should be in proportion to the body
  • Ears - Erect with a heavy base; should not lop
  • Toenails - Uniform color, except in white rabbits
  • Fur - Thick and glossy; same length all over; should roll back when stroked from back to front

Giant Flemish Rabbit Colors

The ARBA recognizes seven colors in the Flemish Giant. Each color has some specifications that judges can look for when evaluating the animal:

  • Black - Coat should be solid black and eyes brown
  • Blue - Coat dark blue and eyes are bluish-gray
  • Fawn - Light gold coat with an undercarriage that is white and brown eyes
  • Light gray - Light gray with black ticking at tips and brown eyes
  • Sandy - Reddish sandy coat with dark ticking and brown eyes
  • Steel gray - Charcoal gray coat with lighter gray ticking and brown eyes
  • White - Pure white coat with pink eyes

Size of Flemish Bunnies

If you want a giant bunny, Flemish rabbits are a great choice. Flemish bunnies are big rabbits. Most fully grown Flemish rabbits weigh around 14 pounds, but there are records of rabbits weighing as much as 21 pounds. Does may weigh just a bit more than bucks. Does also have a dewlap, which is a fold of skin under their chins that gives them a double-chin appearance.

Flemish Giant Temperament and Personality

The Flemish Giant is generally a docile breed, and these giant pet rabbits make good companions and loving family pets. When kept indoors, they will hop around the house and sit on their owners' laps. They can even be trained to use a litter box. However, these rabbits can grow nervous if handled forcibly and can inflict serious scratches and bites if they feel the need to struggle. Always supervise children when handling or playing with rabbits.

The Correct Way to Hold a Flemish Giant

These are big rabbits, so they need a lot of support if you're going to pick them up.

  • Support their upper body with one arm around the chest and front legs.
  • Wrap your other arm around the lower half and make sure you support the rear legs.
  • Hold the rabbit to your chest gently but securely, and make sure you don't squeeze them, or they may panic and struggle.

If they seem nervous at all, reassure them in a soft, calm voice. If this doesn't help them settle in your arms, gently lower them to the ground or into the pen and release them.

Flemish Giant Care and Grooming Needs

Flemish Giants have short fur. They need only minor weekly grooming to keep the coat in good shape, so aim to brush once a week with a slicker brush. However, if the rabbit is molting, brush them twice a week.

Your rabbit will shed its coat twice a year in the spring and again in the fall. The exact time of shedding will vary from animal to animal. You should also trim the tips of their nails occasionally unless the rabbit gets enough exercise to wear them down naturally.

Feeding a Flemish Giant Rabbit

Like most rabbits, Flemish Giants need a diet composed of large quantities of hay, water, and a smaller portion of rabbit pellets. They should also receive fresh vegetables daily and fruit once or twice a week.

Some Flemish Giant breeders recommend free-feeding pellets as they are unlikely to overeat. However, others recommend free-feeding until they are 1-year-old, then giving 1/8 to 1/4 cup of pellets for every five pounds of weight. Offer vegetables at a rate of two to four cups for every five pounds of weight daily, and fruit only in tiny amounts once or twice a week.

Flemish Giant Rabbit Lifespan and Health Concerns

In general, the Flemish Giant is a healthy breed. They live around 5 to 8 years, but these rabbits can live into their teens with proper care.

Common Health Conditions

According to The University of California Agriculture and Natural Resources, larger rabbits are prone to sore hocks due to their giant size and weight. Sore hocks, also known as ulcerative pododermatitis, is a condition caused by standing on wire floors or in unsanitary conditions. It is common in breeds like the Flemish Giant.

Watch Your Fleming Giant's Weight

You'll also want to be cautious about feeding your rabbit too many treats to avoid health issues that can crop up if they become overweight.

Know Your Pet

The best way to keep your rabbit healthy is to know your pet well enough to recognize when they aren't feeling their best. Early treatment can make a difference in recovery. Take care of your Flemish Giant, and they will be an excellent and loving companion for many years.

Special Considerations for Flemish Giant Rabbits

While Flemish can endure cool temperatures, they don't tolerate temperatures over 90 degrees Fahrenheit very well. If they are kept in a cage, they need more room than a smaller breed because of their massive size. Even the door of the cage may need to be larger. They also tend to eat more than smaller breeds.

Breed Origin of Flemish Giants

While no one is 100 percent certain of the origins of this breed, some experts suspect they are descended from breeds raised for fur and meat like Patagonian and Stone rabbits. Others say they descended from the Argentine Patagonian rabbits.

However, Bob Whitman, author of Domestic Rabbits and Their Histories: Breeds of the World, surmises in his book that the Argentine Patagonian hare is actually a rodent, so cross-breeding would be impossible. His theory is that the breed did descend from breeds from the old Flemish region, like the Stone and Patagonian of that area.

Flemish Rabbits Come to America from Belgium and England

The breed came from England and Belgium in the 1890s to America. It wasn't until the early 1900s that people started showing the breed at livestock shows. In November 1915, the National Federation of Flemish Giant Rabbit Breeders (NFFGRB) was formed. When the beginning of ARBA was formed in 1924, NFFGRB became a part of that association. In 1929, the club created breed standards. Today, the NFFGRB continues to work toward improving and promoting the breed.

Breeding Flemish Giants

Does of this breed mature between 8 and 12 months old, or when they reach approximately 14 pounds; this is the perfect time for them to have their first litter. After a doe turns a year old, her pelvic bones begin to fuse. This makes it more difficult for her to deliver her kits, and a difficult delivery can mean death for her and her unborn kits.

Gestation Period for Flemish Giant Rabbits

The average length of pregnancy is 31 days, and most litters average five to a dozen kits, but some litters are slightly larger. Extremely large litters usually mean that some kits won't receive as much milk as the others. Kits that fall behind in their growth before they are weaned typically never develop to their full potential.

How Much Does a Giant Flemish Cost?

You can expect to spend between $20 to $50 for a Flemish Giant, although show-quality rabbits can range from $75 to $300 or more. The Flemish Giant website for breeders and owners provides a helpful chart for determining the costs of owning a Flemish Giant, including housing, accessories, and food. On the low end, you can expect to spend $665 per year caring for a single Flemish Giant rabbit as a pet and around $2,700 for a show-quality bunny.

Decide If a Flemish Is the Right Rabbit for You

If you decide that a Flemish Giant might be a good pet for you, the next step is to make appointments to visit a few breeders and get to know some of these rabbits in person. Although each breed has certain characteristics, each rabbit within that breed is still an individual with its own personality quirks. Take your time before you commit to bringing one of these rabbits home to make sure the two of you will be compatible throughout the years to come.
