Study: Dogs Cry for Joy as Well as Pain
A recent study looked at dogs reuniting with their human friends:
When a person is overcome with emotion, their feelings stream down their cheeks. Even positive emotions can turn on the waterworks, as people bawl when they win awards, express love for their partners, or are reunited with a long-lost friend.
But these feelings-driven tears may not be a wholly human experience. Dogs can also cry happy tears, according to a study published today (August 22) in Current Biology. Although the animals’ eyes don’t overflow, they well up when they’re reunited with their owners after spending even just hours apart, the researchers found. And they have hunch as to why: a sudden increase in oxytocin, the so-called love hormone, named for its predominant roles in social bonding.CHRISTINE WILCOX, “DOGS CRY TEARS OF JOY: STUDY” AT THE SCIENTIST (AUGUST 22, 2022) THE PAPER IS OPEN ACCESS.
That shouldn’t really be too surprising because the fact that humans and dogs can share emotions is part of what forms bonds between us. But it’s good to have a study on record to refer to.

Here are a couple of other recent entries in dog psychology:
We are told, dogs may mourn the loss of other household pets:
According to a survey, researchers found nearly 90 percent of dogs that experienced the death of another canine companion living in the same house showed signs of grief. In the months following their buddy’s death, dogs were less playful and more fearful. They also had reduced appetites and sought more attention from their owners, reports Clare Wilson for New Scientist.
Signs of mourning were stronger in dogs that had an amicable relationship and shared food with the deceased, reports the Guardian’s Nicola Davis. The study was published last week in Scientific Reports.ELIZABETH GAMILLO, “DOGS MAY MOURN THE LOSS OF OTHER HOUSEHOLD PETS” AT SMITHSONIAN MAGAZINE (MARCH 1, 2022)
Dogs’ reaction to emotional loss might be expected. But there are many things they don’t understand. One is that death is permanent (that 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 open access.
