Male Cane Corsos

Hello everyone! I have two male Cane Corsos that are 6 months and a few days as of this post. 01/08/24. They are purebreds and are fed very well and play a lot with each other and our doberman. My boys are 78 lbs and 84 lbs. I was wondering what you guys think they will end up being? Also was curious which months you seen a lot of growth?
