In response to multidisciplinary commentaries on her target article, Kujala addresses foundational questions concerning the nature, diversity, and assessment of dog emotions. While broad agreement exists that dogs experience emotions, disagreement remains regarding their complexity, interpretation, and the influence of human social cognition on emotional attribution.
A central theme of the paper is the importance of accurate emotional estimation. Kujala argues that underestimating canine emotions risks neglect and maltreatment, while overestimating them can lead to unrealistic expectations that increase stress and behavioral problems. This dual welfare risk mirrors challenges seen in early childhood development, where emotional capacity precedes cognitive control.
From a neuroscience perspective, Kujala clarifies that emotions are understood as bodily and neural processes, not abstract mental entities. The current limitation lies not in their existence but in the lack of reliable methods to measure subjective emotional experience in dogs. She emphasizes that physiological, behavioral, and neural indicators provide the most valid scientific access to canine emotions.
The article highlights growing evidence from comparative neuroscience, noting functional parallels between dogs and humans in brain regions involved in emotional processing, including the amygdala, insula, and anterior cingulate cortex. While such findings do not equate to proof of identical subjective feelings, they support cautious, evidence-based inference.
Kujala also stresses the role of human perceptual bias. Interpretation of canine emotional signals varies with experience, expectations, and cultural background. Anthropomorphism, in-group bias, and individual differences in emotional sensitivity can all distort how humans perceive dog behavior, underscoring the need for standardized, objective research methods.
The benefits of comparative cognition are strongly defended. Comparing dogs with humans does not diminish canine experience but provides a structured framework for hypothesis testing, helping distinguish shared evolutionary mechanisms from species-specific emotional processes shaped by evolution, selective breeding, and individual experience.
The paper concludes with clear recommendations for future research: prioritize multimodal measurement, separate emotional expression from subjective feeling, acknowledge human bias, and integrate ethical considerations that recognize canine sentience despite current methodological limits. These guidelines aim to advance both scientific rigor and canine welfare.
