There are very few studies involving dogs’ reactions to a mirror, but Howell & Bennett (2011) recently explored whether dogs could use a mirror to find their owner holding the dog’s favorite toy. The results were different from the ones we report in the present study, with only 2 of 40 dogs appearing to understand that their owner was behind them. However, this previous study only included 2 minutes of exposure to the room before the test condition, and the owner was not asked to spend time in the room with the dog and mirror before the test. This difference in methodology may explain the inconsistent findings. Perhaps, if the dogs in Howell & Bennett (2011) had been given more time to adjust to the room’s set-up, and more experience at observing their owner in the mirror, they would have been more successful.
