The Flemish Giant Rabbit is usually quite docile and mild mannered. However, due to their large size they should be handled with extreme care. These rabbits also require a large amount of space to roam around and make great house pets. They require very little grooming because of their short hair.
The minimum weight requirements for a Flemish Giant rabbit to be entered into a show are 14 lbs for a senior Doe (approximately 1 year old) and 13 lbs for a senior buck (approximately 1.5 years old). Often they can weigh up to 22 lbs with some reports of Flemish Giants weighing up to 28 lbs.
Some rabbit breeders interbreed the Flemish Giant rabbit along with other breeds. They do this to boost the size and growth rate of their herd. Their dietary requirements are very similar to other rabbits. Babies still require a specialized baby rabbit food for optimal health and growth. Adult Flemish Giant rabbits that are not reproductively active require a diet lower in energy to promote long life. In either case the Flemish Giant Rabbit is one of the oldest breeds, primarily because of the attention it gets due to its sheer size.
