I dont think what he did should be illegal to begin with and therefore I dont think drug dogs should even exist because there is no use for them in my opinion. But lets say it was a cadavar dog looking for a dead body. well, technically, the dog's olfactory nerves can only respond to molecules that are OUTSIDE the car. as long as the dog doesnt touch the car, he is only responding to the ambient air. If the dog can be demonstrated capable of pointing to where the scent is coming from (in the same a human can tell where a sound is coming from), then probable cause for a search of where he sais its coming from exists.
