Flemish Giant Temperament

Flemish Giants are also known as Gentle Giants mainly because of their docile nature. These pet rabbits make excellent companions and adorable family pets.

When kept inside the house, they usually hop around and sit comfortably on anybody’s laps. These rabbits can also be litter trained by using a litter box.

They could also easily get edgy when they are handled improperly, though and will bite and may even cause serious scratches whenever they feel the urge to fight.

Therefore, children must be supervised all the time whenever you plan to raise a gentle giant in your home.

Flemish Giant Personality

Despite their enormous size, Flemish Giants are known to be laid-back and docile in nature. They adore their owners and are very friendly with kids.

They also love attention and even sit on the laps of their owners. Flemish Giant Rabbits are still rabbits who easily become wary in new environments.

At first, they will try to get used to the new set-up and assess if something or someone is a threat to their existence. Try to earn their trust by slowly moving around your pet rabbit and respecting your pet’s space and desires.

They are pliant and can be easily trained inside the house. Just try to get to know your pet rabbit to make their personality shine through.

Male and female difference

Male Flemish Giant Rabbits or bucks have broader heads than the female Flemish Giant Rabbits. They can also weigh up to 22 pounds, two pounds more than their female counterparts.

Female Flemish Giants, on the other hand, have large, fur-coated skin or dewlaps just below their chins. These dewlaps are used by the female Flemish Giants to warm their baby bunnies.

Female Flemish Giants could weigh up to 20 pounds.

Flemish Giant Care and Health Concerns

Flemish Giant Rabbits have thick and glossy fur, making them prone to fur mites and ear mites. Therefore, you have to regularly check behind their ears or their furry body.

In case you noticed the presence of ear mites and fur mites on your furry friend, then immediately go to a vet to have it checked and treated.

During summer, Flemish Giants cannot handle the heat well because of their thick furs. You may need to keep your rabbit pet in an air-conditioned room or a well-ventilated area with fans.

You must also offer frozen water bottles for your rabbit friend. If kept inside a cage, you must provide a much bigger area for your Flemish Giant Rabbits than the smaller breeds due to their massive size.

Their size will increase rapidly in the first sixth months of life and when they become older, they are more prone to obesity and all the risk factors that come with it.

Thus, avoid giving them too many treats and provide a bigger size pen with large doors for them to hop around and exercise.

Rabbits that have larger built are also predisposed to sore hocks, a disorder usually caused by standing in unsanitary conditions or wire floors. Hence, floors must be cleaned and well-maintained regularly to prevent rabbits from contracting this disease.

Flemish can also develop health concern common with other rabbit breeds which includes malocclusion, respiratory disease, GI stasis, and uterine cancer. Rabbits are also prone to develop back injury if they are mishandled or accidentally dropped because of their size.

They are also predisposed to heatstroke because of their large and furry body. Make sure they stay in an area where it is not too humid and under 70 degrees Fahrenheit.

It is a must to know these signs of heatstroke such as lethargy, rapid breathing, excessive salivation, ears are going red, and convulsion.

It is best to know your pet rabbits well to recognize when they aren’t feeling better; for early diagnosis and treatment will make a big difference in the recovery of your pet rabbits.

Also, you must talk first with Flemish Giant rabbit breeders in your area, before you decide to bring one to your home, as they need a lot of work. These breeders may give you helpful insights regarding pet care.

Flemish Giant Grooming


Flemish Giant Rabbits have short, thick, and glossy hair. Thus, it only needs minor grooming once a week to maintain the good shape of the coat.

Use a slicker brush to comb your gentle giant’s hair. If your Flemish Giant is molting, then you need to brush two times a week.

Rabbits usually shed their coat two times in a year: in spring and fall. The exact time will vary depending on the animal.

Also, their nails should be trimmed intermittently. Usually, rabbit nails wear off naturally from hopping or exercise.


Because of their enormous size, Flemish Giants consume a lot of food. Their diet must include large amounts of hay and water and high-quality rabbit pellets.

Flemish Giant Feeding

Some Flemish Giant breeders suggest free-feeding your gentle giants with high-quality, commercialized rabbit pellets, as they don’t have the tendency to overeat.

Others also recommend feeding them freely until they reach their first year, then give them a quarter cup of pellets for every five pounds of weight.

You could also give them:

  • carrots
  • parsley
  • cabbage
  • romaine lettuce
  • potatoes
  • corn
  • yams
  • beets
  • papaya
  • pineapple
  • strawberries
  • cantaloupe

But, be sure to introduce them one at a time until their digestive system could accommodate them well.

Vegetables should be given at a proportion of two to four cups daily for every five pounds of weight. Fruits could only be given in small amounts one or two times a week, according to rabbit breeders.

Put a big water bottle in their cage so that they can easily drink or replenish as needed.

  1. I live in Gordon Ga. Close to Macon Ga. I would like some addresses, & phone #s, of Flemish Giant rabbit breeds so I can buy a really big doe, I wantone That is potty trained so I can keep in house & take with me in my truck.

    • Hey Travis,

      The likelihood of finding one that is already trained up for you is pretty slim, but you never know!!

      We recommend checking here for reputable breeders: https://nffgrb.org/breeder-listing

      Definitely do your own due diligence though, and don’t send funds unless you’re 100% sure, and ideally only when you are on site to pick up the rabbit.

    • Hi Margaret,

      Yes, they are fascinating rabbits 🙂

      We’d recommend checking this site here: https://nffgrb.org/breeder-listing

      Breeders are sorted into areas, like Eastern US, Western US, Canada, etc.

      As always though, definitely do your own research to confirm the breeder is indeed in good standing, and don’t send funds without being 100% sure.

      Hope you have success!

  2. The House Rabbit Network in Massachusetts has had both types of giants (and mixes) available for adoption over the past few months. If you aren’t looking for a pedigree this is a great option.

    • It’s not about eating wood, it’s about wearing down their teeth safely because they continue to grow and can become a very serious problem if it inhibits eating. There are lists of safe wood to give them available online or if you ask your Vet. No cedar. I know my rabbits love trimmings from my apple tree and that was on the list (which I can’t find at the moment). I will say that they far prefer a natural piece of wood with spindly branch sticks on it over an expensive chew toy from the store.

    • Hi, Flemish Giants can eat wood they can eat Willow, Apple and pear, Kiln-dried aspen, Birch and poplar, Rose bushes, Maple, Kiln-dried pine, Cottonwood, and Raspberry and blackberry bushes, so Yes they can eat wood.

  3. What % protein is best for their feed pellets? I read 16-18% for Flemish Giants (higher than other breeds), but am concerned that the %18 are starter pellets that may be more alfalfa based and could cause issues for adults. I have 2 spayed females that are 1yr old now. My feed bag has the nutritional breakdown without the actual ingredient list, so I’m contacting the manufacturer. Also wondering about free feeding vs measured pellet feeding.
