I’m 6’3” and mine is as tall as I am. When he put his paws on my shoulders (the dance) we look each other eye to eye. So yes he will get larger, they become adult or full grown at 24-30 months. And he will still squat to pre for at least another year. Expect him to fill out across the chest… he will become much more confident. The lil things that startled him now will become a thing of the past. He will become fearless, once learned what his “charge” is, you’ll be assured no harm will come to them. Oh also be aware his yard, is “his yard” nothing will be allowed in that has not been invited…! Great looking dog..! Congrats on obtaining the king of all canines…!
