The minimum show weight for a Senior (older than 8 months) doe is 14 lbs (about 6.4 kg), and the minimum weight of a Senior buck is 13 lbs (about 5.9 kg)(ARBA Standards of Perfection). As with other "giant" breeds, the Flemish Giant grows slowly. A senior doe can take 1 year to reach full maturity. A senior buck can take 1.5 years to reach full maturity. It is not unusual to see a 10 kilo (22 pound) Flemish Giant, and specimens weighing 13 kilos (28 pounds) have been reported.
