Apparently, this is quite true. According to a UC davis study: which was published in the January issue of Journal Animal Cognition: The performance of drug- and explosives-sniffing dog/handler teams is affected by human handlers’ beliefs.
The study, published in the January issue of the journal Animal Cognition, found that detection-dog/handler teams erroneously “alerted,” or identified a scent, when there was no scent present more than 200 times — particularly when the handler believed that there was scent present.
....
The handlers were told that there might be up to three of their target scents in each room, and that there would be a piece of red construction paper in two of the rooms that identified the location of the target scent. However, there were no target scents — explosives or drugs — placed in any of the rooms....
Although there should have been no alerts in any of the rooms, there were alerts in all rooms. Moreover, there were more alerts at the locations indicated by construction paper than at either of the locations containing just the decoy scents or at any other locations.
