Description:It's a man-steal-dog world. The American Kennel Club says thefts of dogs are up 49 percent in 2011 and on track to quadruple since 2008. Driving the trend: increasing dog prices - now $364 for the average dog and a bad economy. Yorkies and Pomeranians get stolen most. AKC tips include keeping pets on a leash, but Tim Minton believes some dogs are theft proof.(0:58)
