Dogs have emotions that are similar to ours. According to a study, dogs have oxytocin, i.e. “the love hormone”, which is what humans have. In other words, they express compassion, attachment, devotion, and care just like people do — maybe even more so! And some people are lucky enough to capture this expression of love on camera!

We at Bright Side have prepared the most touching pictures that prove how dogs have the biggest hearts.
