Scientists who study non-human animals do not use the word “love” in their published papers. Ironically, most animal behavior scientists were initially drawn to this topic due to their profound and enduring interest in animals.
However, researchers have traditionally been trained not to use anthropomorphic terms such as “love” to describe the emotions of non-human animals. Instead, they use terms like “temperament” and “positive cognitive bias” to avoid anthropomorphism. Though this strict stance on using human terminology for non-humans is starting to soften, due in part to the usefulness of certain terms in describing animal behavior and strong evolutionary reasons to believe that non-human animals are not completely dissimilar to humans.
Observing dog behavior makes it clear that dogs are deeply in love with humans, although some may refer to it as “hypersocial” or “socially obsessed.” There are also questions about how to recognize and define “love” in non-human animals who lack the linguistic capabilities to communicate their emotions.
Various studies have examined dogs’ sensitivity to human emotional states and physiological responses, such as separation anxiety and heart rate changes. These studies shed light on the complex relationship between dogs and humans and suggest that dogs may indeed experience emotions similar to love.
On the other hand, some behaviors that appear affectionate may be vestigial or instinctual rather than expressions of genuine affection. For example, wolves, dogs’ closest ancestors, use behaviors such as “kissing” as part of their natural interactions. Physiological research on heart rate, hormones, and brain activity provides further evidence of the bond between dogs and humans.
Researchers have found that both dogs and humans experience a decrease in heart rate after being reunited, indicating a physiological connection. Similarly, the hormone oxytocin, known for its role in human bonding, is also involved in dog-human bonding.
Furthermore, fMRI images of dog brains show activity in the reward center when dogs are near their owners, suggesting a positive emotional response. This evidence, combined with dogs’ ability to form associations and respond to human cues, implies a deep emotional bond between dogs and humans.
