Jim Dandy:  It's said they do,and I personally believe that they do,but again,if the dog is "working" or doing a job..again,the K-9 unit tracking the criminal,thats the bottom line for it..to do it's job.Hunting dogs track prey,thats their job.Thats what they were bred to do.Dogs in Georgia track and hunt down boar,even tho the wild pig could kill them,they still track and find it.
