A 9 month old bullmastiff female should weigh in the region of 90lbs/40kgs and a male should be around 100lbs/45kgs approx. Give or take 10lbs/5kgs.
Think 10lbs for a month of age up to around 11/12 months. And same for males but add 10lbs to the total.
To the person saying 10kgs, I have a west highland white terrier in fighting fit shape that weighs almost that!! And an 8 month old bullmastiff that weighs 78lbs/34kgs.
Hope that helps
