Deceptive-like behaviour in dogs (Canis familiaris)

Area of Science:

• Ethology
• Animal Cognition
• Behavioral Ecology

Background:

• Deception, involving false signals to alter receiver behavior, is observed even in stable communication systems.
• Subordinate individuals may benefit from deception in competitive interactions.

Purpose of the Study:

• To investigate if dogs are capable of tactical deception by misleading a human competitor.
• To assess dogs' ability to adjust behavior based on human partner roles (cooperative vs. competitive).

Main Methods:

• A three-way choice task was employed, involving dogs, their owners, and two unfamiliar humans (cooperative and competitive).
• Dogs were trained to associate human partners with food provision or withholding.
• Dogs guided partners to one of three locations: preferred food, non-preferred food, or empty.

Main Results:

• Dogs initially led cooperative partners to preferred food more often than chance and the competitive partner.
• In subsequent tests, dogs deliberately led the competitive partner less often to preferred food and more often to the empty box.
• Dogs demonstrated discrimination between cooperative and competitive human partners.

Conclusions:

• Dogs exhibit the capacity for tactical deception, adjusting their behavior to mislead human competitors.
• The findings highlight the flexibility of canine behavior and their sophisticated social cognitive abilities.
