In this innovative psychological review, Savannah Bergeron explored how olfactory-based motivation tests can serve as behavioral indicators of anxiety in dogs. The study focused on modifying the traditional open-field test—a widely used behavioral assessment in rodents—by introducing an odor search stimulus tailored for canines.
Fear and anxiety are closely linked emotions that influence both human and animal behavior. While fear is essential for survival, chronic anxiety can negatively affect well-being. Bergeron’s review aimed to identify measurable behavioral outcomes that reveal how dogs’ motivation to pursue an odor stimulus may vary depending on anxiety levels. By integrating olfactory tasks, the modified test accounts for dogs’ exceptional sense of smell and natural drive to explore through scent.
The study compared findings from canine subjects—particularly military and cancer-detector dogs—with traditional rodent models, assessing whether behavioral patterns associated with motivation and anxiety could be translated across species. Results suggested that dogs’ increased motivation to investigate novel odors could serve as a valuable marker for emotional state, distinguishing anxious dogs from their non-anxious counterparts.
Bergeron concluded that odor-based open-field tests offer a more species-appropriate approach to studying canine anxiety. The findings emphasize the importance of continuing research into scent-driven behavioral methods, which could enhance diagnostic accuracy and welfare strategies for anxious dogs. The paper also calls for refined experimental designs and training programs to further validate these methods across different contexts and dog populations.
