Not that I know a whole lot about them, but there seems to be a huge difference between males and females as far as size and growth. I can't imagine mine reaching 2 ft. by the time it's a year old.
I fell in love with them at a show last year. A lady had an absolute monster female around her neck. Very intimidating look and size but it was an absolute sweetheart! I have yet to see one that is anything but friendly!
