A K-9 with the Maricopa County Sheriff's Office is a big winner.
Tarzan took top honors at the 16th annual Desert Dog Regional Police K-9 Trials, one of the most prestigious competitions among k-9 handlers.
Besides the trials, these working K-9's get a workout on the job. There are 15 dogs assigned to the swat unit, and the unit has averaged 34 narcotics sniffs over the past two years. Last year, the dogs were used in over 100 missions.
