In my limited experience with them,that seems to be an average general description of a vast majority of juveniles.but,some of the people I've spoken to,that have raised them for years,say they seem to mellow out around two-three feet or so,with some regular handling.(I would think there's something to be said for individual variance as well.) I've handled some large adults that were dog tame,and seemed to enjoy the interaction,I've seen others that put you on notice as soon as you enter the room! (*lol* sounds like some Sayi I know!)
