Thanks everyone. He is a super sweet boy, too.
Poppy, he will likely grow another inch in height. He is now 36" at the shoulder. He will certainly fill out and put on more weight. Now he's 150 pounds, but I expect him to reach 180 when fully mature at three years old.
Immisceo, you are very right. And that is one of my other passions concerning this wonderful breed. In some places of Europe, particularly France, Italy, Poland, they are being bred to look like Mastiffs..
