My husky gets wild and destructive at night. What can I do?

Any time a dog exhibits a behavior for which he is rewarded, he is likely to repeat it. If he does something and is corrected (never punished!!!) fir it AS IT IS HAPPENING ONLY, he is unlikely to repeat it. But if he goes wild at night when no one is around and he is not scolded, there is no reason for him to think that there is anything wrong with what he's doing and he will do it again. Reprimanding him after-the-fact is counterproductive, as he will not make the connection and this will only cause him to be anxious and act out more. Your best bet is to put hi in a crate for the night. He may howl and carry on, but you must ignore this (assuming that his bathroom needs, etc. have been met). After a few nights of not getting any attention at all from you when he makes a racket, he will stop and settle down in his crate. The only other option is for you to stay up at night so you can catch him at it and correct him right away. Siberians are very active, and this is not unusual (though it is extreme).
