As above. I have known a fair few of this mix and it is a complete lottery. Some have been absolutely lovely, very gentle, sensible dogs and eminently trainable but on the flipside, I know two brothers who are nothing short of uncontrollable - the energy of a super high drive working dog, VERY strong, basically crazy. They are raced alongside huskies, and it takes two people to hold each dog on the way up to the starting line. That is pretty much the same all the time - the owner can just about walk them in headcollars but only just. Last time I saw them run with no other dogs, the owner came very close to flying off the back of her rig with the force of their pull as they shot off the starting line! More husky in terms of personality/breed traits but more GSD in looks.
Most seem to err towards the more sensible side but it is still a gamble.
