For millennia, canines have held the esteemed title of ‘humankind’s closest companion,’ a substantial duration fostering mutual understanding. Nevertheless, a recent investigation emanating from Arizona State University’s dedicated canine science laboratory suggests that our capacity to accurately interpret our dogs’ emotional states might not be as refined as we presume.
It transpires that our personal emotional disposition can subtly color our perception of their feelings.
Researchers specializing in animal behavior, Holly Molinaro and Clive Wynne, unveiled a study earlier this year that demonstrated how owners’ assessments of their dogs’ emotions can exhibit a bias contingent upon the contextual circumstances.
For illustration, one might be more inclined to infer that their dog is experiencing elevated joy at a park setting compared to during a routine bath, irrespective of the actual signals their canine counterpart is conveying.
“Despite individuals believing they possess insight into their dog’s emotional landscape, our findings indicate that people tend to make judgments about a dog’s emotions based on the prevailing situation,” Molinaro articulated when the initial research was disseminated.
The subsequent work by Molinaro and Wynne delves into an additional determinant that could potentially influence human interpretation of canine affect: the observer’s own prevailing mood.
To rigorously examine this hypothesis, 300 university students were enlisted to appraise video segments depicting dogs exhibiting objectively positive, neutral, or negative emotional expressions. To preclude any confounding effect of the dogs’ environments on viewer interpretations, the backdrops were rendered entirely black.
In an initial experimental phase, participants were subtly induced into positive, neutral, or negative affective states through exposure to imagery unrelated to animals, such as landscapes and human portraits. This methodological approach has been substantiated by numerous academic inquiries in psychological research, supporting its efficacy studies.
While this affective priming successfully modulated participants’ self-reported emotional experiences, it surprisingly yielded no discernible impact on their perception of the dogs’ emotional states as presented in the videos.

In a subsequent experimental design, Molinaro and Wynne devised a suite of species-specific priming materials for human viewing. This comprised images exclusively of dogs, carefully selected from resources such as the Open Affective Standardized Image Set. This particular priming intervention also proved effective in eliciting the intended positive, neutral, or negative moods among participants, yet its influence on their capability to discern canine emotions presented a perplexing outcome.
Intriguingly, participants who had been primed to experience positive emotions exhibited a greater tendency to perceive the dogs as exhibiting sadness, whereas those in the negatively primed cohort were more inclined to interpret the dogs’ demeanors as happier than they objectively were.
These findings suggest that our inherent biases in interpreting canine emotional expressions are more intricate than Molinaro and Wynne initially posited, underscoring the need for continued investigation.
“In the United States alone, it is estimated that there are 80 million dogs. Our team is dedicating significant effort to fostering optimal lives for both people and their canine companions,” Wynne remarked.
It is well-established that investing time in comprehending and addressing a dog’s specific needs enhances the likelihood of cultivating a secure and resilient pet.
Research of this nature holds considerable potential to advance animal welfare initiatives and bolster efforts aimed at the rehabilitation of pets exhibiting aggressive tendencies, anxiety, or stress.
