When a handler and his/her dog are a good fit, have the time, resources, and enthusiasm to continue in the program then the handler must take and pass a background check, complete paperwork, and begin the training program. Training is conducted weekly, and requires traveling to work with handlers over a wide geographic range. Candidate handlers have a lot to learn about search and rescue, dog training, documentation, search strategy, olfaction and scent theory, working with a chain of command structure, and teamwork. There are numerous evaluations and skills tests to complete along the way: fitness, incident command system classes, first aid and CPR, among others. Expect to take as much as 2 years before being ready to take a certification test. This is a long endeavor that will demand your full attention and time.
