The husky is a runner, both fast burst and marathon, a natural stalker and hunter, stubborn, virtually untrainable unless it's for running and usually a marvelous family dog. Hates cats! The pit side brings into mix the potential for overt or suppressed violent insanity. The only 100% solution is a trip to the woods and a 22LR in between the eyes. I recommend a rifle and not a handgun.
If you want to attempt the humane thing, go to a farm supply store and get the gear for an electric fence made to keep cattle in a field. Much less $$$ and more effective than the cute fence and collar things from pet supply big box store. If you have cattle, string the single wire about 3ft high and for dogs 1ft high. There are latches to engage/disengage at gates. Oh, it's great fun for kids as well! When no adult is looking, a kid will touch the wire once or twice. After that it's all fun and games though! Double dog dare a friend, younger sibling or cousin to touch that wire. Great childhood fun! Yes, I'm warped, grew up on a ranch.
Touch? Triple dog dare to pee on the fence!
