The American Kennel Club gives up to 28 lb (13 kg) for males and up to 28 lb (13 kg) for females. Individual dogs can fall outside a breed range, and a mix or a dog from working lines may be larger or smaller.
When is a French Bulldog fully grown?
On this curve a male reaches half of adult weight at about 18 weeks (4 months), 90 % at about 54 weeks (12 months) and 95 % at about 76 weeks (18 months). On this curve a female reaches half of adult weight at about 17 weeks (4 months), 90 % at about 55 weeks (13 months) and 95 % at about 74 weeks (17 months).
