If you are a member of a search and rescue team, yes. Though sport tracking is not the approach typically taken or even police tracking as most searches involved contaminated and aged starts - typically a SAR dog is used either as an on lead trailing dog or an offlead airscent dog.
Sometimes you can work one on one with a police department and not be part of a team but teams usually can work with multiple departments and you should consider the need of some way to ensure liability coverage /workmen's comp.
Some teams, however, do not allow dogs with any bite training. Some police departments don't want to field any dogs with bite training for search. Perceived Liability...plenty of threads on that...no intent to start another.
