Like any pet, these furballs require a special diet for optimum health. A healthy, balanced diet contributes immensely to your rabbit’s longevity. Overweight or underweight bunnies are more likely to die younger than the average Flemish giant rabbit lifespan.

  • Pellets: Flemish rabbits need high-quality pellet feed to stay healthy. A high-quality rabbit pellet should have a nice fresh smell to it. It will also be green to brownish in color and be completely or at least primarily dust free. These pellets should be fed at 1 tablespoon per kg of body weight.
  • Hay: Hay provides your pet rabbit with the necessary fiber. Timothy hay is the most recommended hay for rabbits. Its fiber and calcium content is ideal for the needs of your bunny. Hay should make up 85% of their diet.
  • Vegetable: Feed your bunny a pile of healthy fresh leafy greens and herbs the size of its head each day.
  • Treats: Occasional treats like seedless apples, beet tops, banana, seedless berries, cucumbers, dandelions, carrots, fruit tree leaves, twigs, mango, Romaine lettuce, pineapple, radish, and raisins are all great treats for your pet rabbit. Just make sure not to give them too many treats, which can lead to obesity.By feeding your bunny a poor diet, it can become malnourished or overweight, which may lead to gastrointestinal stasis and ultimately death.


Equally important is the right environment and proper care. If, for instance, your rabbit friend lives outside, they might fall victim to predators such as foxes. As for indoor rabbits, if unsupervised, they may chew through electric cables or eat poisonous plants leading to an early death.


Even giant breeds require regular exercise each day to keep healthy and in good shape. They need plenty of space to hop around, or they are at risk of developing health problems.

Another good option is the use of a spare room, enclosed porch, or storage area that is devoted partially or completely to rabbit life. Just make sure to rabbit-proof the room by covering electrical outlets and putting away everything you do not want to be damaged. As with all rabbits, they need physical and mental stimulation. So create tunnels, places to dig, hide and forage, and provide them with a variety of pet-friendly toys.

How to Take Care of These Giant Rabbit Breed

If you are a new Flemish rabbit owner, we strongly recommend following these tips to ensure your bunny lives a long, happy, and healthy life.

Daily Care

As with all pet animals, Flemish bunnies are no exception to the rule of being dependent on their human owners, not only to protect them from predators and mother nature but also for their day-to-day care.

Conduct regular checks on your bunny in search of scratches, blisters- abscesses, missing fur, matted fur, open wounds, mucous on or around their ears, eyes, or nose, and dry or dry crusty skin. Also, check to see whether they are drinking their water, if they’ve eaten their feed since you last fed them if they are acting normal, whether they are grinding their teeth or making funny or unusual sounds, and whether they are moving much or not other things.

Each and every one of these things is important as they are often an indication of an upcoming or underlying problem, some of which can be life-threatening. The sooner you catch the problem, the higher their chances of recovery.


On average, a rabbit’s pen should be cleaned at least once a week. This includes changing bedding-covered floors, throwing out the old litter, and washing their drop pans and drinkers. Doing this not only helps you kill the odors of rabbit urine but also helps to prevent disease.

Next, you also need to ensure you brush out your bunny’s fur. This not only helps maintain the fur in good condition, but it also helps them release natural oils, which are used to keep their skin healthy. Fur brushing also provides a great way to examine your bunny for missing fur, dandruff, and parasites, which can quickly get out of control if not treated as soon as possible.

Neuter or Spay

Spaying or neutering your giant bunny provides an effective way to increase your bunny’s lifespan. Neutering is done on male rabbits and involves the removal of testicles. Testicles produce testosterone which causes stress. Stress can put a strain on your bunny’s heart, leading to health problems. Neutered male rabbits lack excessive amounts of testosterone, leaving them calmer and less aggressive. As a result, neutered bunnies generally live longer.

Spaying female rabbits are the removal of ovaries and the uterus. Female rabbits are prone to different cancers, and spaying helps eliminate this risk.

Provide Enrichment

Enrichment activities make your rabbit’s life more interesting. Some ways of enriching your bunny’s life is through toys, socialization, exploration, and individualized play with their owners. If it lives indoors, allow your bunny to explore the house as long as it is bunny-proofed. If you have a garden or yard, consider setting up a run to allow your bunny some outdoor time. Generally, keeping fit is essential for optimal animal health. So exercise will help keep your bunny healthy, happy, and alive for longer.
