Sorry I've been posting like crazy, I've just got a lot of things to post about

On the 4th of July Alaska is absoulutly terrified! The fire works really scare him to death. Whenever he hears them, he starts howling, and barking, and hiding. Last July he jumped the kennel fence and chewed the door knob until he got inside. Is there something we can do to prevent this? Some kind of medicine or something...?
