What Is a Flemish Giant Rabbit?

Flemish Giant Rabbits are truly giant, compared to your average bun! The common cottontail is a mere 15 to 17-inches long, and 2.5 to 5.5 pounds. Compared to these little guys, the 2.5 foot-long, 12-20 pound Flemish Giant Rabbit is a veritable bear of a bunny… a soft, cuddly bear! 

Flemish Giants are not found in the wild naturally. They are thoroughly domesticated and have been for a very long time. In fact, the Flemish Giant is one of the oldest breeds in history.

They are descended from ancient giant rabbit breeds, like the European Patagonian and the Stone Rabbit, some experts believe. 

These breeds were raised for fur and meat purposes, and are now extinct, sadly.

The Flemish Rabbit first appeared in Belgium, in the 16th century. In 1893, the extraordinary animals were exported from England to the US. In 1924, they became an official charter breed of the American Rabbit Breeders Association (ARBA).

Owners quickly found the Flemish Giant Rabbit to be intelligent and well-behaved, and easy to train as well. The Flemish giant is a gentle giant, and naturally calm and peaceful.

Just keep in mind that they must be held carefully, so they do not spook. Their legs are quite powerful, and, when frightened, they tend to kick.

Treat your Flemish Giant Rabbit right, and they will reward you with a temperament that is as sweet as can be

You can find these beautiful short-haired rabbits in a variety of colors, which are: white, sandy, light gray, steel gray, blue, and black.

In the wild, a Flemish Giant Rabbit would probably not survive. They have been domesticated for too long now. Despite its size, the Flemish Giant Rabbit is still a prey animal and looks like an easy snack.

When left unattended outdoors, the Flemish Giant Rabbit is in danger from dogs, predatory birds, foxes, and more.

In summation, Flemish Giant Rabbits were literally bred to be pets and should live safely in a home (or in a secure outdoor enclosure).

How Can I Help My Flemish Giant Rabbit Live Longer?

Flemish Giant Rabbits are not as long-lived as the common cottontail. They live 5 years on average, sometimes more.

Cottontails live to be 9 or more. You can give your Flemish Giant Rabbit the longest possible lifespan with the proper care and a bit of love!

Flemish Giant Rabbits Require Lots of Space

This is one of the most unique requirements of the Flemish Giant Rabbit!  Most buns can be perfectly at home in a cage or hutch. For the Flemish Giant Rabbit, however, these enclosures are much too small.

They are made for 15-17” long rabbits, after all. Instead, your Flemish Giant Rabbit will probably require a kennel. There are also some extra-large cages available online. 

Some even opt to dedicate a room in the house to their bun (where they will have their bedding, litter box, and so on)!  

Flemish Giant Rabbits Need Plenty of Exercise

Along with a big living space, Flemish Giant Rabbits must have plenty of room to exercise. This means that you will frequently need to let them out of their enclosure to stretch, play, and explore. Just make sure that the area is rabbit-proof! 

Fortunately, compared to their smaller cousins, the Flemish Giant Rabbit is calmer and less active.

Frequently Clean Your Flemish Giant Rabbit Cage

One con of the Flemish Giant Rabbit is that, due to their size, they eat more, and create more waste. This means that you will need to clean their living area more frequently than you would for a little bun. 

As with any rabbit, hygiene is absolutely key to the health of the Flemish Giant Rabbit overall.

Flemish Giant Rabbits Must Be Clipped and Groomed For Their Health

Flemish giant rabbits have very luxurious fur that is nice and thick. While this is a lovely attribute, it also means that you will need to groom them often. Otherwise, they will ingest too much fur when they groom themselves and develop what is called ‘fur block.’ 

Flemish Giant Rabbits also have thick nails, due to their size. These will need to be clipped every once in a while, to avoid a condition called ‘sore hock.’

Flemish Giant Rabbits Need A Positive and Peaceful Home 

You must make sure not to expose your Flemish Giant rabbit to excessive activity or noise. Like any rabbit or prey animal, they are extremely sensitive.

They must have an environment that is positive and peaceful for their well-being, and in order to sleep and relax.

Outdoor Flemish Giant Rabbits Must Be Properly Secure

Flemish Giant Rabbits can be kept outdoors, on a few conditions. The biggest concerns are the elements and predatory animals. Provided that it is comfortable, with bedding, a litter box, and so on, you can keep your Flemish Giant Rabbit in a kennel.

To protect from predatory animals, like dogs and foxes, this kennel will need to be durable and appropriately closed-off.

Birds of prey may also attack, so the kennel will need a roof. Additionally, the roof will protect from rain, wind, and the like.

Breeding Decreases The Flemish Giant Rabbit Lifespan

Breeding any animal decreases its lifespan, especially rodents, like rabbits, guinea pigs, and the like. Should you wish to breed your Flemish Giant Rabbit, this is something that you will want to be aware of.

To Live Their Longest, Flemish Giant Rabbits Must Eat Properly

Since Flemish Giant Rabbits are up to 10 times the size of your average rabbit, they need much more food to consume. Should you be considering adopting a Flemish Giant Rabbit, you will have to buy food often to keep them in stock! 

Like most rabbits, Flemish Giant Rabbits should eat mostly hay. Timothy hay is a particularly nutritious choice. Recommended is to buy this in bales, to save on money, effort, and time.
