I trained my dog to find drugs.

I used to let the dog smell drugs and at the same time give the dog a tasty dog treat and what I would do is associate the two together and then I would take the sweet treat away from the drugs and then when the dog found it I would give the dog the treat and then I would go around a forest and get the dog to look for drugs people stashed and the best area was an overgrown area near the Bridge at Inverness next to a salmon factory which we used to drive vans full of packaged luxury salmon which I would sell to a guy in the local pub.
