Mastiff growth

I know that mastiffs generally don't mature until 18 months. From your experience, at what age do they stop growing in height? I think I've read somewhere that 9 months is the age when they will reach adult height and that after that they fill out and gain muscle. Does that sound right?

I'm trying to gauge Millie's eventual size-ish. She seems quite small.... she's a bullmastiff cross dogue, although is such bizarre colouring that i'd guess there's something else in the mix (although her parents' owners say absolutely not).

She's 7 months now, weighing in at 28kg which is around 63lbs. That seems quite small I think.

Any thoughts on growth rate?

Kryten (EM) was about 12 months old when he stopped getting taller. I do know that his growth plates had completely closed at 13 months which the surgeon who did his elbow surgery was a little surprised by.
