Sniffers dogs usually fail

According to a 2010 Chicago Tribune public-records examination of suburban Chicago traffic-stop drug searches, they found a funny fact: that sniffer dogs are usually wrong; a 56 percent of all positive signals by dogs yielded no contraband and also the 73 percent failure if the driver was Hispanic.

What would intails this? Have dogs a biased and/or opinated way to do their job or it's just that hispanics tend to smell like drugs because of some enviromental reasons?
