At Working K9, we've been training detection dogs for X years and throughout our time we've improved our processes to get the most reliable results.  Our new Advanced Scent Training Boxes take the dog from their first day of scent training all the way to practical drills.

We start with the round opening at the top of the box.  There are 2 sizes of openings, adult and puppy.  A puppy may get their head stuck in the adult opening so we've included a smaller insert for puppies so only their muzzle fits.   
 
Our introduction to detection is to load the scents into the box using our in-house developed scent tubes, and then we play the 'Elevator Game'.     <insert more details>
