hello every one , could you please tell me how tall my beloved bo , who is a bullmastiff bitch she is 14 months old now and is 23 inch tall and would like to know when she will stop growning.......

Hi Guest, according to the breed standard, adult Bullmastiff bitches should be 24''-26'' once fully grown. Bo will probably achieve full height by around 12-18 months, but she will continue to develop and mature in body for a while longer, perhaps up to 3 years old.
