Query: Worthless on German Shepherd

I have an INSANE German Shepherd that paces, 'air snaps', whines and howls non-stop. Its beyond irratating. We will be flying him on a 14hr flight and I bought these pills to keep him from ripping his kennel to shreds and roaming the cargo bay of the plane. He ALWAYS tears out of his kennel and hurts himself severly...even with zip ties. Needless to say, at 2 pills nothing...still paces & bites the kids when they move. 3 pills he lays down occasionally when NOTHING in the house moves...but as soon as the kids move an inch he is up scratching, grunting and being annoying. I'm worried to increase the dose more. He is only 65lbs. But I'm thinking for the flight we will give him 5 pills. *shakes head*
