A Single Purpose K-9 is trained to detect one category of odor, whether that be all the components that make up explosives, various narcotics, cell phones, molds, human DNA, etc. AMK9 does not cross train our canines, which means we do not train a single purpose explosive detection dog on any other category of odor.
A Dual Purpose K-9 is trained on detection of odor and on patrol work. A patrol K-9 is specifically taught to catch an assailant, but only on command. AMK9 Patrol and Dual Purpose dogs are trained to stop immediately on command, in mid-chase, if necessary.
