Emotions are critical for humans, not only feeling and expressing them, but also reading the emotional expressions of others. For a long time, this ability was thought to be exclusive to people; however, there is now evidence that other animals also rely on emotion perception to guide their behavior and to adjust their actions in such way as to guarantee success in their social groups. This is the case for domestic dogs, who have tremendously complex abilities to perceive the emotional expressions not only of their conspecifics but also of human beings.

The emergence and the development of the ability to read emotions from individuals bring clear evolutionary advantages. Being able to recognise the emotional expressions and states of a different species, for instance humans, might be vital for functional social interactions. Living in a complex social world requires sophisticated knowledge about other individuals and this information is what allows animals to predict the behavior of others. Social information is critical to adult humans in various ways, including making decisions and defining whether an individual might gain help or resources from others or not, and the same might be true for dogs.

The Importance of Emotion Perception

The ability to perceive and understand emotions is a crucial aspect of social cognition, not only for humans but also for many animal species. In the case of domestic dogs, this skill can provide significant evolutionary advantages and facilitate their complex social interactions. Understanding the emotional expressions and states of a different species, such as humans, can be vital for dogs to engage in functional interspecies communication.

Evolutionary Advantages

The emergence and development of the ability to read emotions from individuals can bring clear evolutionary advantages. By being able to recognize the emotional expressions and states of others, animals like dogs can better predict the behavior of those around them, allowing them to adapt their own actions accordingly. This sophisticated knowledge about the social environment is critical for navigating the complexities of the modern world, whether it’s for humans or their canine companions.

Facilitation of Social Interactions

Living in a complex social world requires an in-depth understanding of other individuals and their behaviors. The

ability to perceive and interpret emotional cues can provide valuable information that allows animals to anticipate the actions of others, make strategic decisions, and engage in more effective social interactions. For dogs, this skill can be particularly important in their relationships with humans, as it enables them to better navigate the intricate dynamics of interspecies communication and cooperation.

Defining Emotions in Animals

Emotions can be broadly defined as complex multifaceted psychological phenomena that influence the management and the control of behavior. Emotions play such a crucial role that their experience, in terms of both quality and intensity, can interfere in how events are registered in our memory. Dogs, in their day-to-day lives, are not only passive of their own emotional experience but are also active subjects for expressing their emotions in a communicative way and, further, for recognising the emotions and emotional expressions of others.

Multifaceted Psychological Phenomena

Emotions are not simple, one-dimensional states, but rather multifaceted psychological phenomena that involve a complex interplay of physiological, cognitive, and behavioral components. From an evolutionary perspective, emotions serve crucial functions in guiding behavior, facilitating social interactions, and promoting survival.

Influence on Memory and Behavior

The experience of emotions, whether positive or negative, can significantly impact how events are encoded and remembered. Emotions can influence decision-making, motivate actions, and shape the way individuals respond to their environments. Understanding the role of emotions in animal behavior and cognition is crucial for improving animal welfare and fostering stronger bonds between humans and their animal companions.

The Science of Pet Emotions

Dogs are very well adjusted to their multispecies groups, families and life dynamics. However, to what extent does appropriately perceiving the emotions of the people they interact with play a critical role to their success? Does reading emotions allow them to live functional social lives?

Dogs as Active Emotional Communicators

Domestic dogs are known to be very good readers of human communicative cues such as pointing and looking, even from very young ages or with little experience with people. Dogs have also been shown to be sensitive to people’s attentional state, showing distinct behavior depending on the person’s attention direction and attention availability.

The Unique Dog-Human Relationship

A great deal of dogs’ social living occurs in mixed-species groups. In fact, humans and dogs are more than sympatric species, i.e. there is more than territory overlap in place. In fact, they establish long lasting, dynamic, complex and mutually advantageous relationships. These two species have co-existed for at least 10,000 years with genetic evidence suggesting more than 20,000 years of divergence between the ancestor of the modern grey wolf and the ancestor of the domestic dog. During this shared evolutionary history, dogs may have been selected, probably unintentionally, for handling the complexities of heterospecific social relationships.

Reading and Responding to Human Emotions

Emotional cues, however, are more subtle and their perception can comprise different processes. Despite its recency, the study of emotion perception in animals, especially non-primates, has been growing strong and rapidly. Dogs have been empirically shown to be particularly sensitive to human emotions. They discriminate and show differential responses to emotional cues expressed through body postures, facial expressions, vocalizations and odors, and emotional cues can influence their behavior. Moreover, current research has shown that cultural as well as developmental factors can influence these abilities.

Sensitivity to Communicative Cues

Dogs’ social cognition facilitates the interaction with humans, and the ability to read and respond appropriately to emotional cues may have been – and may still be – key for the establishment of these interspecific bonds. In this context, it becomes crucial to investigate how dogs respond to emotional expressions and whether and how dogs use the emotional information from others in social situations mediated by distinct emotional valences.

Perception of Facial Expressions and Body Language

Dogs discriminate and show differential responses to emotional cues expressed through body postures, facial expressions, vocalizations and odors, and emotional cues can influence their behavior. Understanding the emotional capacities of our pets and other animals can help us improve animal welfare and build stronger bonds between humans and their animal companions.

A Functional Approach to Emotion Perception

A functional approach refers to the history of the behavioral trait as well as to the consequences of possessing such a trait. The use of emotional information from conspecifics and, in the case of the dog, heterospecifics, may be seen as an adaptation for handling the complexities of the social environment, regardless of its underlying causes.

Strategic Decision-Making

Affiliative behaviors are more flexible when they involve strategic decision-making, i.e. making choices conditional to the behavior of the members of one’s group. This allows animals to anticipate someone’s future behavior and respond accordingly, which is cognitively demanding yet highly advantageous.

Anticipating and Responding to Behavior

The ability to anticipate someone’s future behavior and respond accordingly is crucial for successful social interactions. By decoding the emotional expressions of others, animals can better understand their feelings and predict their likely actions. This interspecies communication allows for more effective strategic decision-making and improved human-animal bonds.

Using Emotional Information in Problem-Solving

There is enough evidence to allow conclusions about the expression and the perception of emotions by dogs. Several animal species are known to be sensitive to emotions. However, being able to obtain information from emotional expressions is not necessarily functional. Dogs’ social cognition facilitates the interaction with humans, and the ability to read and respond appropriately to emotional cues may have been – and may still be – key for the establishment of these interspecific bonds. In this context, it becomes crucial to investigate how dogs respond to emotional expressions and whether and how dogs use the emotional information from others in social situations mediated by distinct emotional valences.

Cognitive Biases and Decision-Making

Researchers have found that dogs can acquire relevant information from emotional displays, match these with information about emotional expressions and consequences, and use this to predict the potential behavior of others to inform their own decision-making. This suggests that dogs can infer implicit information from human emotional expressions and use it in a functional way. Understanding the emotional capacities of our pets and other animals can help us improve animal welfare and build stronger bonds between humans and their animal companions.

Influence of Emotional Valence

By examining how dogs respond to emotional expressions and use emotional information from others, we can gain deeper insights into the role of emotional valence in their problem-solving and decision-making processes. This knowledge can inform more compassionate pet care practices and enhance our understanding of interspecies communication and the strengthening of the human-animal bond.

Measuring and Assessing Animal Emotions

Understanding the emotional capacities of our pets and other animals is a crucial step in improving animal welfare and building stronger bonds between humans and their animal companions. Researchers studying horse welfare don’t simply focus on fleeting emotions like happiness or sadness. Instead, they’re interested in a horse’s overall emotional health – how good or bad it feels in the long run.

Observational Methods

To measure a horse’s contentment, researchers often look at its posture, the position of its ears, and how attentive it is to its surroundings. Factors like appetite and immune function can also shed light on a horse’s overall wellness. Certain chemicals in the blood can even point to persistent stress.

Neurological and Physiological Indicators

Recent studies have taken a more technological approach, with researchers developing a simple, portable device worn as a headset to measure a horse’s brainwaves. Horses that roamed with their herd, grazing outdoors at will, had more theta brainwaves, which in humans seem to reflect a calm, well-being. In contrast, animals that lived in solo stalls with little contact with other horses had more gamma brainwaves, which in some studies have been linked to anxiety and stress.

By exploring a range of observational, neurological, and physiological indicators, researchers are gaining deeper insights into the emotional experiences of our animal companions. This knowledge can help us create more compassionate and enriching environments for the pets and animals we care for.

Implications and Future Directions

Studying what animals feel and experience is a challenge, as feelings are personal. People can try to learn how animals feel based on clues from their bodies and their behaviors, but doing science about this is a bit strange, as the key thing is unknowable. However, researchers are getting insight into a wide range of animals. For instance, recent studies hint that picking up a mouse by its tail can ruin its day. Meanwhile, an unexpected sugar treat may boost a bee’s mood. Crayfish might feel anxiety. Ferrets can get bored. Octopuses — and perhaps fish — can feel pain. Knowing all this could begin to change how we treat animals.

Improving Animal Welfare

Future studies exploring dogs’ sex, breed, age and length of time living with the owners, as well as assessing other species, will build on these findings and allow a deeper understanding of the underlying mechanisms of emotion recognition and inference in animals. This knowledge can help us improve the welfare of our pets and other animals by tailoring our care and interactions to their emotional needs.

Understanding Interspecies Communication

Exploring the science of pet emotions, animal behavior, and interspecies communication can provide valuable insights into the complex relationships between humans and their animal companions. By decoding pet emotions, understanding their psychology, and recognizing the unique ways they express themselves, we can foster stronger, more meaningful bonds and improve the overall well-being of our animal friends.

Conclusion

The results of this study demonstrate that dogs can acquire relevant information from emotional displays, match these with information about emotional expressions and consequences, and use this to predict the potential behavior of others to inform their own decision-making. This suggests that dogs can infer implicit information from human emotional expressions and use it in a functional way. Understanding the emotional capacities of our pets and other animals can help us improve animal welfare and build stronger bonds between humans and their animal companions.

Future studies exploring dogs’ sex, breed, age and length of time living with the owners, as well as assessing other species, will build on these findings and allow a deeper understanding of the underlying mechanisms of emotion recognition and inference in animals. By decoding the pet emotions, we can gain valuable insights into animal behavior, pet psychology, and ways to better understand pets and enhance interspecies communication.

Ultimately, this research highlights the remarkable emotional intelligence in animals and the importance of recognizing and responding to their emotional needs. By fostering a compassionate approach to pet care and improving the human-animal bond, we can create a more harmonious and fulfilling relationship with our beloved animal companions.
