Study: dogs cry with joy and pain
A recent study looked at reunions of dogs with their human friends:
When a person is overwhelmed with emotion, their feelings run down their cheeks. Even positive emotions can ignite the aqueducts, as people bawl when they win prizes, express their love for their partner, or reunite with a long-lost friend.
But those emotionally-driven tears may not be an entirely human experience. Dogs can also cry tears of joy, according to a study published today (August 22) in Current Biology. Although the animals’ eyes don’t bulge out, they do gush when reunited with their owners after spending even a few hours apart, the researchers found. And they have a hunch for the reason: a sudden increase in oxytocin, the so-called love hormone, named after its predominant role in social bonding.
This shouldn’t really be too surprising because the fact that humans and dogs can share emotions is part of what bonds us. But it’s good to have a recorded study to refer to.

We are told, the dogs can cry loss of other pets:
According to a survey, researchers found that nearly 90% of dogs that suffered the death of another canine companion living in the same home showed signs of grief. In the months following their buddy’s death, the dogs were less playful and more fearful. They also had reduced appetites and craved more attention from their owners, reports Clare Wilson for New scientist.

The reaction of dogs to emotional loss can be expected. But there are a lot of things they don’t understand. The first is that death is permanent (this concept is an abstraction). The dog in the video above needed a lot of intervention to just move on and find a new life. The study at Scientific reports is freely accessible.
