Dog Health Questions: Dog training (drug sniffing)?

so my friend was in class and we were talkin about dogs.. he said that he knows some one whos been training for about 10+ years and he has a german shepherd and taught him how to sniff out a drug in a week... i told him thats very surprising because germans shepherds can learn fast.. hes say no german shepherd could learn it just in a week and i said that its not hard to train a gsd to do things like that....... im i right?

• How you train drug or bomb dogs is simple.
  
  Take a ball, generally a tennis ball, put the desired material into the ball. Then teach to the dog to play with and look for his ball. Then they just tell the dog to find his ball, and he finds the bombs/ drugs thinking it's his ball.
  
  Training a tacking blood hound is harder, because they have to ignore scents, and follow just one. They also will sniff the air and the ground to figure out which way the thing being pursued will head, trying to cut it off.


• i have trained my gsd's in 3 sessions. and they can track and search the item i wanted them to look for. now a week is just too long if you want the 3 sessions to be made everyday; thats only 3 days :) have to post video of my dogs in actual law enforcement work so you could see. :)
