He is still a puppy and has a lot of time left to grow...Brutus just turned 14 mnths and I have been noticing he is filling out more now! The first year was growing up and the 2nd is filling out...
I can't "see" your pictures..but you've ot a lonnnnnnnnnnnng time to wait before you know what he will look like when finished! Just enjoy him and I'm sure he will be perfect.
