Dogs Cry Tears Of Joy EXPLAINED

Share this post on:


The age-old question of whether dogs cry tears like humans has ignited passionate debates among pet owners. Some dismiss it as mere anthropomorphism, while others firmly believe that our beloved canine companions possess and express human-like emotions. In this article, we’ll dive into the fascinating world of dog emotions and present scientific evidence supporting the idea that dogs indeed shed tears of joy when they reunite with their owners. Recent research published in the prestigious journal Current Biology sheds new light on this intriguing topic. Let’s explore the tears of joy that our furry friends may shed and the profound emotional bonds they share with us.

Scientific Discovery of Dogs’ Tearful Reunions


Recent scientific research, published in the esteemed journal Current Biology, has shed light on this intriguing topic. The study reveals that many dogs indeed shed tears when they are reunited with their owners, even after just a few hours of separation. What’s even more fascinating is that the intensity of this tearful expression of joy is closely tied to the levels of oxytocin, often referred to as the love and bonding hormone.

The research team behind this groundbreaking discovery is led by Professor Takafumi Kikusui from Azabu University in Japan. His inspiration for this study came from a personal experience with his own pet poodle. Six years ago, he noticed that her demeanor was notably relaxed while nursing her puppies, and tears frequently welled up in her eyes during these moments. This observation sparked the idea that oxytocin might play a crucial role in the production of tears in dogs.

The Tears of Joy

During their investigation, Professor Kikusui and his team made some intriguing discoveries. They found that dogs release a more significant quantity of tears when reuniting with their owners after being apart for five hours, as opposed to the initial five minutes of separation. This suggests that the phenomenon is specific to the bond between dogs and their owners.

Interestingly, tears did not appear in dogs that were reunited with familiar individuals who were not their owners, highlighting the unique nature of the connection between dogs and their human companions.

Protective and Nurturing Behaviors

But why do dogs cry when they see their owners? The researchers concluded that this emotional display has evolved in dogs to elicit protective and nurturing behaviors from their human companions. When owners see tears in their dogs’ eyes, they tend to react protectively and offer increased attention and care to their pets. It’s a heartwarming example of the reciprocal nature of the bond between dogs and humans.

Human Response to Dog Tears

Additionally, the study delved into how people respond to dogs with tears in their eyes. Surprisingly, the results showed that a significant 15% of respondents expressed a stronger desire to adopt dogs displaying tears compared to those without such emotional displays. This demonstrates the powerful connection between humans and their four-legged friends and the emotional impact that dogs have on us.
