Dogs Can Cry Tears of Joy

New Research Confirms What Dog Owners Have Always Known

A new study published in the journal Current Biology has confirmed what dog owners have always known: dogs can cry tears of joy. The study, which was conducted by researchers at the University of Tokyo, found that dogs produce tears when they are reunited with their owners after being separated for a period of time.

Tears of Joy

The researchers believe that the tears are a way for dogs to express their happiness and excitement. They found that the tears contain a protein called prolactin, which is also found in human tears when we cry. Prolactin is thought to play a role in bonding and attachment, so it makes sense that it would be present in the tears of dogs who are happy to be reunited with their owners.

Conclusion

This study provides further evidence of the strong bond that exists between dogs and their owners. It also shows that dogs are capable of expressing a wide range of emotions, including joy and happiness. So next time you see your dog crying, don't be alarmed. They're probably just expressing their love and joy for you.
