Do dogs get jealous?

It is commonly assumed that jealousy is unique to humans, partially because of the complex cognitions often involved in this emotion. However, from a functional perspective, one might expect that an emotion that evolved to protect social bonds from interlopers might exist in other social species, particularly one as cognitively sophisticated as the dog. The current experiment adapted a paradigm from human infant studies to examine jealousy in domestic dogs. We found that dogs exhibited significantly more jealous behaviors e.g., snapping, getting between the owner and object, pushing/touching the object/owner when their owners displayed affectionate behaviors towards what appeared to be another dog as compared to nonsocial objects. These results lend support to the hypothesis that jealousy has some “primordial” form that exists in human infants and in at least one other social species besides humans.

Drop Outs and Bloopers: Behind the Scenes of Canine Science

The growing field of canine behavior and cognition research is not built on the backs of lab beagles. Instead, research depends on the kindness and interest of dog owners who sign up their dogs to join any of the canine studies around the globe.

So whenever I meet a dog in NYC, I’m thinking, “Would your human companion be interested in signing you up for a study at the Horowitz Dog Cognition Lab?” And, just as important, “Would you, Mr. or Ms. Dog, be interested in participating in a study?” Nine out of ten times (not an exact science) the answer is yes.**

But dog participation doesn’t always go as planned. Which leads to one of the most interesting yet overlooked sections of research papers — the section that reports the dogs who didn’t make it into the final results. A blooper reel of sorts. These nuggets hidden in dense research papers offer little windows into the world of dogs and canine research methodologies. Why did a dog not perform according to plan? Was the dog not interested in playing along with the tasks required by the study? Or maybe the owner or experimenter goofed up the execution. Let’s take a look:

Dogs yawn more often in response to owners’ yawns than strangers

Aug. 7, 2013 — Dogs yawn contagiously when they see a person yawning, and respond more frequently to their owner’s yawns than to a stranger’s, according to research published August 7 in the open access journal PLOS ONE by Teresa Romero and colleagues from the University of Tokyo.

Experts dispute validity of statistics on dog bites

“Those who study which dogs bite most and why agree that firm breed-based statistics are tough to come by. Whether such numbers are relevant is where they differ.”

A few steps to control your dog’s bark


A nuisance barker is made, not born. As I discussed in the column on digging, dogs that don’t have jobs or a way to expend physical and mental energy are going to find a release somehow.”

Do Dogs Laugh?

“For many years psychologists and behavioral biologists agreed that laughter was a unique emotional expression found only in humans. However, as the study of animal emotions expanded this idea was called into question. The Nobel Prize winning ethnologist, Konrad Lorenz suggested that dogs are capable of laughing. He says that it is during play that dogs actually appear to laugh.”

Keeping peace in two-dog house a full-time job

“Dogs are territorial, and in homes with two or more dogs there is one that’s the lead dog. Except in our home. Shadow, our very frail 14-year-old Labrador, is the grand dame of the house. After all, she is the eldest. You wouldn’t tell Queen Elizabeth she wasn’t the head of the monarchy, would you? Well Kodi would.

Kodi, the nearly 3-year-old Corgi, is a male. Shall I just stop here?”
