Doc get a life, go back to a home made bow and arrow and stop using all modern equipment if that is how you feel. Tracking dogs are just another tool in a hunters arsenal that they can use to recover game. I track for other hunters and have done so for 9 years now. I can tell you that there have been plenty of deer that would not have been recovered with out the use of a tracking dog. Here in the south the temps during bow season can be very warm. The difference in a few hrs can make the difference if the meat is good or bad. I have also tracked out to 36 hrs just so the the hunter who had spent many hrs already on his hands and knees looking could get closer on his hunt. I have also track for people who were color blind. It is a proven technique for recovering game that can not be located by eye tracking. Rouffly half the states now allow tracking dogs in one fashion or another with other majior problems.
