Apparatus for training a subject dog to perform target odor detecting operations within a completely confined compartment, which comprises a partial compartment having at least three angularly different surfaces to define an interior. The surfaces are sufficiently long to provide a subject dog located within the interior with a sensation of being at least partially confined. An air inlet is defined by a configuration of the partial compartment, by which odor laden air is introducible into the interior and is detectable by the nose of the subject dog. A dog interfaceable member is operatively connected to the partial compartment and activatable upon detection of a predetermined target odor.
