This study aims to investigate the relationships and interactions within French military human–canine teams conducting olfactory searches. A thematic content analysis has been carried out based on 16 interviews with handlers from the French Army. Three themes are presented, focusing on 1) canine handler, a distinct specialty; 2) missions, as the real-world for the military canine team; 3) training dogs. The relationships and interactions between humans and dogs within canine teams are partly shaped by the context of the missions, by the military institution, as well as by the particularities of dyad members. Degraded environments, risks, and death are essential determinants in the preparation and implementation of canine teams, as well as in the relationships established within the partnership.
