Can Dogs Experience Jealousy?

Is your dog green with envy? Mad at you? Are his feelings hurt? New study opens up a window into the mind and emotions of our best friends.

Anyone who thinks dogs can’t feel jealousy has never met my dog. My French Bulldog, Huggs, is very well-behaved. Trained as therapy dog, he is quiet and low-key, that is until you are not paying "enough” attention to him. He is well known in the family for wanting something anytime you are doing anything else. Whether that means climbing onto your newspaper or casually leaning backwards across your lap so you can’t possibly use your laptop, making dolphin-esque noises when you stop touching him, or squeezing himself between my husband and I, he is either extraordinarily jealous, or the biggest attention-whore known to dog-kind, or both. I’ll go with both.



Don't mind me, I'm sure you would rather pet me than take this call. Huggs taking over laps and cellphones.


As a kid we had Simon the Lhasa Apso who was happy as can be until we introduced our second dog, a Shih Tzu named Wally. When Simon wasn’t hiding under the bed in protest, he took to stealing things from the bedrooms and would run by tossing it in the air so everyone would come after it and away from whatever adorable thing Wally was doing. Was he jealous? If he was a kid, we probably would have sat down with him and told him that we loved him and his new brother equally and they get the same amount of attention. But if you are a first born child, you probably felt what Simon felt: that it simply wasn’t true (did I mention I’m the baby of my family?)  

Jealous Dog: What to Do When Equal Isn't Enough>> 

I actually had this discussion about dogs and jealousy with my family just the other day. The common consensus was that jealousy is a complex emotion and therefore reserved for human feeling (and squabbling,) not something dogs would concern themselves with.  But a new study from PLOS ONE, might make you rethink how dogs think.  

Adapting a test that has been used to determine jealous behavior in human infants, Psychologists from the University of California, San Diego researchers were able to determine that dogs do in fact feel jealous.

Researchers videotaped 36 small breed dogs reacting to their owners ignoring them and instead displaying affection to an animated, stuffed dog that barked, whined and wagged its tail. During these interactions with the plush pet, over three-quarters of the real dogs pushed or touched their owners. The dogs also made attempts to get in between the stuffed animal and the owners, or went as far as to growl at the imposter.

The group of dogs were also tested with a children’s books and a plastic jack-o-lantern, which their parents pretended to care about more than them. Although they displayed some of the same jealous behaviors, it was much less than with the fake dog, suggesting, dogs jealousy is triggered by social interaction and not merely by their owners' ignoring them for an inanimate object.

Introducing a Second Dog>> 

The findings mirror those of studies of 6-month-old babies who had jealous reaction to their moms interacting with a doll, but were less concerned about moms interacting with a book.

Psychologist Christine Harris, who led the study, says she's been studying jealousy for many years — but in humans.

So what does she think of the dogs?

The fact that these dogs seemed like they were trying to draw their owners away from the stuffed animal indicates that they're feeling something very similar to human jealousy, Harris says.

But in the end (as convincing as it seems) the study still doesn't prove that dogs feel jealousy. "The problem is that [the researchers] didn't look at how dogs would react just to those objects," Laurie Santos , director of the Canine Cognition Center at Yale University  tells NPR. Jealousy is a complex emotion. If we find out that dogs feel the same way, "either jealousy is less complicated because animals show it, or animals are more complicated than we thought."

While the study might not be conclusive, there is no doubt that whether your call it jealousy, fear or sadness, dogs feel something when someone or something gets in the way of the love and attention they deserve. This site is filled with information helping dogs to adjust to life changes and additions of new family members, be it human, dog or other. Just like with humans, some dogs are likely to feel the pull of emotions greater than others.

My name is Gavin Vanessa From UK, I read some testimonies about a love spell caster by DR KAMA on how he has helped lots of people in bringing back their ex lovers within 48 hours, Sincerely I was just thinking if that was real and if this man could really help bring back my lover whom I love so much. I decided to contact him because I love my husband very much and we have been apart for a couple of months I really missed him so much, I have tried all other means to get him back but couldn’t. I contacted: and he told me that my ex will come back to me in the next 48 hours,DR KAMA released him up to know how much i loved and wanted him. And opened his eyes to picture how much we have share together. My ex is now back to me again.As I`m writing this testimony right now I`m the most happiest girl on earth and me and my husband is living a happy life and our love is now stronger than how it were even before our break up.All thanks goes to DR KAMA for the excessive work that he has done for me by helping me to get back with my ex husband. I would like to drop DR KAMA mail address and hope you see this testimony and contact him if you have a lover that you really want back so badly, His mail:( )or call him +2348162573264

Realistically it's probably more of a territorial thing, but I like thinking she's jealous. :)

The single best example of dog jealousy is my fox terrier Boofa who shares the house with a labrador Max, four guinea pigs and a tropical fish tank. If my dad or I are cleaning the fish tank, petting Max or cuddling a guinea pig Boofa will always try to get more attention and if he doesn't get instant attention he sits at your feet looking sad. Both my dogs will often come and sit between me and my boyfriend, Boofa especially gives him very dark looks from across the
My parents had to give their dog to my grandparents after my bother was born (he is my younger brother) because Gremlin became aggressive. Up until I was born he was more or less my parents first child and when I was born he got less attention and once my brother was born he got a bit less. Once Gremlin was given to my grandparents he settled down a lot more because he was once again an only
After spending my whole life (I'm 23) with dogs I can say that I am 100% sure dogs feel jealousy and some handle it better than others.

Dogs Absolutely DO Experience Jealousy! As Well As Grief, etc.

I only Adopt Older "Rescue" Dogs. My First Dog, F, was the Love of My Life. Then, came S. They immediately fell in Love! When F passed over to the Rainbow Bridge, S Grieved terribly. Thinking another Dog would Help Us both, I adopted H. S Did Not Like or Accept H. She would sit and stare at Me if I held Him. When H passed away, S acted like He had never been here. S wants Me All To HerSelf, now! If I pick up My iPhone, She actually Sighs - and Quite Loudly! I'm Sure that She feels I Should Be spending that time Brushing or Petting Her! It's a Good Thing that She Is Such a SweetHeart!
