The dogs are extremely in reliable. They are trained when they hit the get a treat. They did a study a while back. 6 cops with 6 dif dogs. They told the cops there were drugs in one room of the house. The dogs hit on every part of the house. There were no drugs in the house what so ever. This is just one study on this issue. The dogs are found to follow physiological cues of their handlers. If the cops think you have drugs a lot of dogs will hit. They do find a lot of stuff and I'm not down playing a dogs ability but they are easily manipulated. My favorite is the false alert on the cars front bumper out of dash camera range. I had to go to a tire shop in junction Texas to dismount tires because the dog said we had drugs in the rims.
