Overview
The Flemish Giant is one of the largest domestic rabbit breeds, with adults typically weighing 6kg or more.
They are usually docile and tolerant and are often described as gentle giants.
Their size brings large demands for space, food, housing and veterinary cost, plus a shorter lifespan typical of giant breeds.
They suit experienced keepers who can genuinely accommodate them.
Housing
Standard rabbit cages and hutches are unsuitable.
A Flemish Giant needs free-roam room access or a pen of at least 5m² per pair, with a large secure run for daily exercise and oversized litter trays, hides and water bowls.
Soft, well-cushioned, non-slip flooring is vital, as their weight makes them prone to sore hocks.
Keep them cool and well-ventilated, since large rabbits overheat easily and struggle above about 25°C.
Diet
Unlimited grass hay forms the foundation, supplemented with generous daily leafy greens and a measured pellet portion scaled to their body size.
They eat more than small rabbits, but hay must still dominate to protect teeth and gut.
Provide fresh water in heavy, tip-proof bowls.
Avoid overfeeding pellets and sugary treats; obesity in such a large animal strains joints and worsens the risk of sore hocks and gut problems.
Health
Sore hocks (pododermatitis) are a major concern given their body weight, so soft flooring and clean bedding are essential.
Giant breeds are also prone to heart problems and have shorter lifespans than small rabbits.
Dental and gut-stasis risks apply as in all rabbits.
Vaccinate against RHD1/RHD2 and myxomatosis, neuter for health, and budget for larger drug doses and a rabbit-experienced practice.
Temperament
Flemish Giants are generally calm, easy-going and affectionate, and often tolerate handling well, though their size and strength mean they must be supported carefully and are not ideal for small children.
They are social and benefit from a bonded, neutered companion, ideally another large rabbit.
A relaxed giant enjoys gentle, floor-level company and tends to be docile with patient keepers.
