Retriever Rescue

A man gets on an airplane, and is very surprised, when the seats at the side of him are taken by a man and his golden retriever, on asking him why he has been allowed to bring his dog onto the plane.The man explains, that his dog is a sniffer dog, and they have had information that, smugglers have targeted this plane, so when they are airborne he will set the dog to work, and if he finds anything he will let him know, and he will inturn inform the captain, who will radio ahead and have the police waiting when they land.Soon after reaching the cruising altitude,the dog gets of the seat and walks down the isle, he stops at a lady's seat, licks her hand and returns to his seat barking once, the officer writes the lady's seat number down, and explains that means shes smuggling marijuana, the dog then sets off again, he stops at a mans seat and rolls over then returns to his seat and barks twice, that mans smuggling cocaine.So he writes his seat number down ,the dog sets of again this time he goes to the back of the plane, runs round in a circle three times, then scampers back as fast as he can, and climbs onto the seat and poos all over it. Why did he do that asks the first man. The officer replies I think hes found a bomb.
