What was done
Fourteen domestic dogs (*Canis familiaris*) were videotaped in an experimental paradigm testing the origin of the owner-perceived "guilty look." Trials systematically varied whether dogs disobeyed an owner's command not to eat a treat while left alone, as well as the owner's belief/knowledge regarding whether the dog had eaten the treat. Videotapes were coded for behavioral elements associated with a guilty look.
What was found
The abstract reports no numerical values. It found no significant difference in guilty-look behaviors between dogs that actually disobeyed versus those that obeyed. Instead, guilty-look behaviors occurred more frequently when owners scolded their dogs, and this effect of scolding was most pronounced when dogs had actually been obedient rather than disobedient.
Why it matters
This study demonstrates that the familiar canine "guilty look" is likely a submissive response to owner affect and scolding cues rather than an indicator of self-conscious emotional guilt or awareness of a misdeed.
Limits
The sample size was very small (14 dogs), and the abstract does not provide exact quantitative metrics, statistical test values, or effect sizes. Long-term owner-dog relationship variables and diverse environmental contexts outside the laboratory trial were not evaluated.
