Yeap, My Husky can be destructive if left along and not excercised. I learned that the hard way.. lol Huskys are very active dogs, they need to be walked ran played with every day or you will start seeing destructive behavior just because they are bored. Pack oriented training is a must with huskys like Ryan said. And yes they make horrible guard dogs. They are most most friendliest dogs you will ever own, they are very family/pack oriented. Leash training has to be done with anyone that walks the husky. Just because my husky is leash trained with me, doesn't mean she will behave the same with someone else. Also for crate/cage training, it is easier if you put a heavy duty tarp over the cage to make it dark when she is in the cage because more close to a den environment. I say heavy duty tarp because if you use anything else, they will pull it into their cage and destroy it. After they get use the the cage/crate you wouldn't need it anymore. Sibe Huskys are great pets if trained and treated right. I wouldn't trade my Sibe for anything in the world.
