What is a Flemish Giant Rabbit?

The Flemish Giant is an old breed of domestic rabbit that originated in the Flanders region of Belgium. As their name suggests, Flemish Giants are known for their large size and weight. They are considered a gentle "gentle giant" breed that can make great pets for rabbit lovers who have plenty of indoor and outdoor space.

Flemish Giants are one of the largest breeds of rabbit in the world. The average weight range is 10-14 lbs for does and 13-17 lbs for bucks. Some specimens can grow even larger than that though, with the largest on record weighing in at a whopping 22 lbs! Despite their intimidating size, Flemish Giants have a reputation for having a calm, friendly temperament. They tend to be more easy-going and tolerant of handling compared to smaller breeds.

The Flemish Giant has a semi-arch body type with powerful hindquarters that allow it to attain great size. It has a large, broad head and straight ears that stand erect. The fur is short, glossy, and dense. Recognized coat colors include black, blue, fawn, light gray, sandy, and steel gray. Show quality specimens will have bold black markings called "mask, ears, mane". The Flemish Giant was first bred as early as the 16th century and continues to be popular among rabbit enthusiasts today.

Flemish Giant Rabbit Characteristics

Here are some key characteristics of the Flemish Giant breed:

  • Large size – Weights range from 10-22 lbs depending on gender. Length can reach up to 30 inches.

  • Semi-arch body type – Powerful hindquarters and a strong, broad back. Helps support their heavy build.

  • Calm, friendly temperament – Typically docile and tolerant of handling despite their imposing size. Make good pets.

  • Pointed face and large ears – Ears stand fully erect and their wedge-shaped head gives them a alert expression.

  • Short, dense coat – Fur is glossy and rollback, laying close to the body. Comes in a variety of color patterns.

  • High nutritional needs – Require plenty of hay, pellets, and fresh veggies to stay healthy. Prone to obesity.

  • Slower maturing – Not fully grown until 1-1.5 years old. Lifespan averages 5-8 years.

  • Gentle "gentle giant" attitude – Enjoy human interaction and generally get along well with other pets when properly introduced.

The Flemish Giant's size, temperament, and appearance make them stand out. While their care requires more space and food than smaller rabbits, they reward their owners with their calm, friendly personalities.

The Personality of the Flemish Giant

The Flemish Giant is known for having a gentle, calm demeanor despite its imposing size. Here are some of the most notable personality traits of this large rabbit breed:

  • Patient – Flemish Giants tend to be very tolerant of handling and interaction with humans. They don't startle or scare easily.

  • Curious – This breed often appreciates exploring new environments. They are intelligent and like to investigate.

  • Friendly – Generally responds well to human interaction. Enjoys being petted and given attention.

  • Placid – Has a mellow, easygoing attitude. Usually not high-strung or nervous like smaller breeds.

The Flemish Giant's serene personality makes them ideal for households with older, considerate children and adults. Their patience and friendliness ensure they usually enjoy interacting with their human caretakers. Monitoring their health and providing plenty of space are the biggest challenges for owners.

How Big Do Flemish Rabbits Get?

The Flemish Giant is one of the largest rabbit breeds in existence. So just how big do these bunnies get? Here's a look at their size range:

  • Adult Size: Typically 8-16 pounds, but may reach 22 pounds.

  • Length: Can reach up to 30 inches long from head to tail.

  • Height: Standards allow up to 23 inches tall when posed with ideal body type.

  • Breed Categories: The ARBA recognizes Lightweight, Mediumweight, and Heavyweight size categories.

  • Lightweight – Ideal weight is 9-12 lbs for does/11-14 lbs for bucks.

  • Mediumweight – Ideal is 11-14 lbs for does/13-16 lbs for bucks.

  • Heavyweight – Ideal is 13+ lbs for does/15+ lbs for bucks.

  • Largest Recorded: The largest Flemish Giant on record reportedly weighed in at a whopping 22 pounds!

  • Maturing: Reach full adult size after 8-14 months. Growth rate impacts final size.

  • Gender Size Differences: Bucks are often 1-2 pounds heavier on average than does.

So while 10-14 pounds is typical, through selective breeding some Flemish Giants can tip the scales over 20 pounds. Yet due to their calm temperament, they often don't seem as large as they really are! With good care, diet, and genetics, this breed can reach an impressively massive size.

What is the Average Weight of a Flemish Giant Rabbit?

The average weight for a Flemish Giant rabbit is:

  • Does: 10-14 lbs

  • Bucks: 13-17 lbs

So for does, the average tends to fall around 12 pounds. And for bucks, the average is about 15 pounds.

However, weights can vary quite a bit based on:

  • Age – Flemish Giants keep filling out until around 8-14 months old.

  • Genetics – Some bloodlines produce larger rabbits than others.

  • Diet – Getting proper nutrition supports ideal growth.

  • Exercise – Regular activity helps prevent obesity.

  • Health issues – Sickness or conditions may inhibit growth.

The largest Flemish Giants can potentially reach 20+ pounds, but this is less common. The ideal show weight for the largest "Heavyweight" category is 13+ pounds for does and 15+ pounds for bucks.

While their huge size is impressive, pet Flemish Giants should be fed a measured diet to prevent unhealthy obesity. Targeting the ideal average weight for their gender allows them to live happier, healthier lives.

Flemish Rabbit Enclosures

Due to their large size, Flemish Giant rabbits need plenty of room both inside their homes and in any outdoor enclosures. Here are some ideal housing setups:

  • Large dog crate or puppy pen – Provides an indoor area with high walls they cannot jump over.

  • Exercise pen – Fences in an area for safe outdoor playtime. Look for tall, heavy panels.

  • Rabbit condo – Multi-level cage systems that provide both housing and play spaces.

  • Rabbit-proofed room – Allow supervised run of a rabbit-proofed room or living space.

  • Custom built hutch – All-weather outdoor hutches with connected runs offer protection.

  • Minimum cage sizes: At least 6-8 square feet for single rabbit, 10+ square feet for pair.

  • Outdoor space: A secure run or penned area for exercise. At least 8-10 square feet.

Flemish Giants can be litter trained to eliminate in a box, keeping their living area tidy. Provide plentiful hay in a rack or pile for bedding and to encourage natural grazing behavior. Ramps, tunnels, boxes, and ledges provide enrichment. Whatever the setup, ample space keeps active Flemish Giants happy and healthy.

Indoors vs Outdoors

Flemish Giant rabbits can be housed either indoors or outdoors, each with their own considerations:

Indoor Housing Benefits:

  • Protection from predators, weather, temperature extremes
  • Closer interaction and bonding with humans
  • Easier to rabbit-proof environment
  • Litter training possibility
  • Limit exposure to pests like fleas, ticks, and mosquitoes

Outdoor Housing Benefits:

  • More space for large enclosure
  • Fresh air and sunshine
  • Natural rhythms of daylight
  • Cooler in summer heat
  • Owners less impacted by noises, odors

Tips for Indoors:

  • Rabbits kept indoors need daily playtime in an exercise pen.
  • Litter training allows more freedom when supervised.
  • Rabbits will chew housewares, so cables must be protected.

Tips for Outdoors:

  • Hutches should have retreat areas to get away from elements.
  • Predator-proof any outdoor enclosures using buried fencing.
  • Bring rabbits indoors if extreme temperatures occur.
  • Outdoor rabbits still need daily human interaction.

Both indoor and outdoor housing can work well. Consider the rabbit's personality, climate, space available, and your preferences when deciding between them.

Bedding Requirements

An appropriate bedding substrate is important for absorbing messes, providing traction, and cushioning bones. Here are good bedding options for Flemish Giant rabbits:

  • Grass hay – Orchard grass, timothy, brome, oat. Avoid alfalfa.

  • Straw – Provides warmth and cushioning. Must be kept dry.

  • Fleece blankets – Machine washable and cozy. Watch for chewing.

  • Aspen shavings – Soft, low-dust wood shavings.

  • Recycled paper bedding – Made from recycled paper or cardboard.

  • Avoid cedar shavings – Cedar oils are toxic to rabbits if ingested while grooming.

Key Guidelines:

  • Provide at least 2-3 inches of bedding material.
  • Spot clean wet areas and add fresh bedding regularly.
  • Change out all bedding completely 1-2 times per week.
  • Allow access to hay in litter box, pile, or rack at all times.

Enough quality bedding keeps rabbits comfortable, promotes natural behaviors like digging, and makes cleaning up easier. Choose substrates that are absorbent, safe if ingested, and dust-free.

Litter Tray Bedding for Flemish Rabbits

An appropriately sized litter box with suitable litter is key for litter training success. Here are tips:

Litter Box Size:

  • Box should be large enough for the bunny to fit inside.
  • Corner style pans work well for Flemish Giants.
  • Consider getting a cat litter box or cement mixing tub.

Litter Options:

  • Paper pellets made from recycled paper.
  • Aspen pellets are soft on paws while controlling odor.
  • Grass hays like timothy or brome make great "hay litter".
  • Avoid clumping cat litter which can be harmful if ingested.


  • 3-4 inches of litter is ideal. This allows natural digging behaviors.
  • Add fresh litter to maintain depth as it gets sifted through.
  • Deeper litter also helps absorb large quantities of urine.

With the right set up, most Flemish Giants can be litter trained. The key is providing an extra-large, comfortable space filled with appealing, bunny-appropriate litter. This encourages them to return to the box repeatedly.

Cleaning up After a Flemish Giant Rabbit

As one of the largest breeds, Flemish Giant rabbits produce correspondingly large amounts of waste. Here are some tips for cleaning up after them efficiently:

  • Spot clean litter boxes daily – Scoop out soiled areas and wet clumps.
  • Full litter box change 1-2 times per week – Dump entirely and sanitize box before refilling.
  • Sweep up stray pieces of poop daily – Scatterless commercial litters can help.
  • Wash any bedding in enclosure 1-2 times per week – Machine washable fleece or disposable paper-based beddings are easiest.
  • Disinfect surfaces weekly – Use vinegar, diluted bleach, or commercial pet disinfectant.
  • Bathroom accidents – Absorb urine puddles with paper towels then clean with pet odor/stain remover.
  • Provide larger litter box – The bigger the box, the more they can go between changes.
  • Try high-sided pans or cement mixing tubs for extra capacity.

Daily quick cleans prevent odor build up and ammonia accumulation from large volumes of urine. Deep litter boxes, easy to change beddings, and cleaning supplies make cleaning up after a Flemish Giant manageable.

Grooming Requirements

Grooming a Flemish Giant rabbit helps keep their coat and skin healthy. Here are grooming tasks rabbit owners should perform:

  • Brushing – Helps remove loose hair and redistribute natural oils. Brush 1-2 times per week.

  • Nail trimming – Clip excess nail growth every 4-6 weeks to prevent injury, overgrowth, or splayed feet.

  • Ear checks – Clean inside ears gently with cotton balls to prevent infections from buildup.

  • Shedding assist – During heavy sheds, brushing or pet shedding tools can help remove loose coat.

  • Sanitary trim – Keeping fur trimmed neat around the rear prevents soiling and urine scald.

  • Molting assist – Can pluck some loose fur during major molts if overgrooming becomes an issue.

  • Foot pad trim – only if excess fur between pads causes slipping on smooth floors.

  • Hygiene – Clean litter box, bedding, dishes regularly to prevent diseases.

Daily pets and cuddles help monitor their health. Grooming is an important part of connecting with rabbits, and keeps their coat, skin, feet, and ears in great shape.

Grooming Tools for Giant Rabbits

Having the right grooming supplies makes caring for a Flemish Giant's coat easy. Recommended tools include:

  • Slicker brush – Removes loose hair and untangles fur. Use weekly.

  • Shedding blade – Metal shedding tools work well during heavy molts.

  • Wide-tooth comb – Helps smooth coat and catch shed fur. Good for use on face.

  • Nail clippers – Get guillotine or scissor-style specifically for rabbits.

  • Styptic powder – Stops bleeding if you trim nails too short.

Optional extras can include:

  • Soft grooming gloves – Lets you gently pet and remove loose fur.

  • Vacuum brush – Helps suck up shed clumps during shedding season.

  • Ear cleaner – Diluted vinegar or saline to gently wipe outer ears.

  • Trimming scissors – For sanitary trim and foot fur only if needed.

  • Deshedding spray – Can help loosen old coat before brushing.

Having the right tools on hand makes grooming sessions quicker and easier on both you and your Flemish Giant. Invest in quality rabbit-safe supplies.

What to Feed a Flemish Giant Rabbit

The Flemish Giant's large size requires a nutrient-dense diet to stay lean and healthy. Here are ideal dietary components:

  • Grass hay – The majority of diet should be timothy, orchard, brome etc. Provides fiber and promotes healthy teeth and GI tract.

  • Leafy greens – At least 2 cups daily of lettuce, kale, herbs, spring greens, etc. Provides vitamins, minerals, and hydration.

  • Pellets – 1/4-1/2 cup quality pellets per 6 lbs body weight daily. Look for timothy or alfalfa based.

  • Fresh vegetables – 1-2 cups chopped veggies like carrots, celery, peppers, squash, etc. Provides beneficial nutrients.
