Can Dogs Limbo? Dogs' Perception of Affordances for Negotiating an Opening

Area of Science:

• Animal Behavior
• Cognitive Science
• Comparative Psychology

Background:

• Limited research exists on canine body size perception.
• Understanding how animals perceive their size is crucial for cognitive science.

Purpose of the Study:

• To investigate domestic dogs' (Canis lupus familiaris) judgment of their body size.
• To assess dogs' ability to adapt their behavior to changing environmental affordances.

Main Methods:

• Two experimental studies were conducted involving dogs navigating openings of decreasing height.
• A second study examined dogs' behavior when carrying an object (a stick) in their mouth.
• Latency to approach and body adjustments were measured.

Main Results:

• Dogs showed significantly longer latencies to approach openings that were nearly too small to fit through.
• The sequence of body adjustments for aperture negotiation was consistent across individual dogs.
• Preliminary findings indicate altered approach behavior when carrying an object, which improved with experience.

Conclusions:

• Results support the hypothesis that dogs possess an understanding of their own body size.
• Dogs appear to perceive and act upon environmental affordances in an action-scaled manner.
• This study provides evidence for sophisticated spatial cognition in domestic dogs.
