Which rabbit is normally considered to be the largest breed of the species?

The Flemish Giant rabbit is a very large breed of domestic rabbit (Oryctolagus cuniculus domesticus), normally considered to be the largest breed of the species. Flemish Giants are a utility breed, and are most commonly bred for fur and meat. The breed is also known for its docile nature and patience in being handled, resulting in the large animals commonly being kept as pets.

As one of the largest breeds of domestic rabbit, the Flemish Giant is a semi-arch type rabbit with its back arch starting behind the shoulders and carrying through to the base of the tail giving a "mandolin" shape. The body of a Flemish Giant Rabbit is long and powerful, with relatively broad hindquarters. The fur of the Flemish Giant is known to be glossy and dense. When stroked from the hindquarters to the head, the fur will roll back to its original position.

Bucks have a broad, massive head in comparison to does, and can take 1.5 years to reach full maturity. Does may have a large, full, evenly carried dewlap (the fold of skin under their chins), and can take 1 year to reach their full maturity.

Flemish Giant Rabbits weigh 15 pounds on average, though the biggest ones can weigh up to 22 lb, and the longest one on record (in fact, holding the record for the longest rabbit in the world of any kind), measured about 4 feet 3 inches long.
