Research Proves Dogs Experience Jealousy Emotion

Many dog owners have witnessed moments when their loyal pets display clear signs of jealousy. This natural canine behaviour often emerges when owners focus their attention on another dog, a person, or even an object, which the dog perceives as a rival for affection. Recent research has gone beyond anecdotal evidence, scientifically confirming that dogs do indeed experience jealousy – an emotion once thought exclusive to humans.

A Range of Dog Breeds Studied in Canine Jealousy Research

For a long time, assumptions about the emotional lives of dogs were cautious. Animal behaviourists and vets debated whether dogs truly experienced human-like emotions such as jealousy. However, studies conducted by the University of California, San Diego, have provided compelling evidence that jealousy is a primordial emotion shared by humans and social species like dogs.

The research involved 36 dogs of various small to medium breeds, whose average size was under 35 pounds and below 35 inches in height, including these breeds:

• Belgian Malinois puppies
• Chihuahua puppies
• Boston Terrier puppies
• Dachshund puppies
• Maltese puppies
• Havanese puppies
• Pomeranian puppies
• Miniature Pinscher puppies
• Pug puppies
• Shetland Sheepdog puppies
• Welsh Corgi puppies
• Shih Tzu puppies
• Yorkshire Terrier puppies
• Several mixed breeds

How the Study Demonstrated Canine Jealousy

Researchers observed each dog in their home environment to ensure authentic behaviour before introducing an animatronic dog that barked, whined, and wagged its tail like a real canine. Dogs' reactions when their owners interacted with this "robot dog" revealed strong signs of jealousy.

When owners focused their attention on the animatronic dog, dogs displayed behaviours such as barking, growling, and attempting to disrupt the interaction by physically intervening. In contrast, when owners were absorbed in a book, dogs also showed signs of jealousy, but to a lesser degree, signalling that social interaction triggers this emotional response more than inanimate objects.

An interesting observation was many dogs sniffed the robotic dog's behind first, mimicking real-life canine greeting behaviour, which supports dogs distinguish animate beings and respond emotionally to social rivals.

Is Canine Jealousy Innate or Learned?

This study, alongside other research, suggests jealousy is not merely a learnt behaviour but a deeply embedded, primordial emotion. Just as 6-month-old human infants show jealousy when their parents focus on a realistic doll, dogs too exhibit this emotion instinctively to protect social bonds.

Responsible dog owners often recognise that their dogs can get jealous in varied situations—whether directed towards other dogs, people, or even children—expressed through vocalisations, body language, and attempts to monopolise their owner’s attention.

Recognising and Handling Jealousy in Dogs

Understanding that dogs experience jealousy helps owners respond with empathy. Owners should avoid exacerbating jealous behaviour by giving attention fairly and creating positive associations when new social interactions occur. This approach aids in nurturing confident, emotionally balanced dogs.

Conclusion

Dogs are emotionally complex companions who share many feelings with humans, including jealousy. Ongoing research enriches our understanding of dog psychology, strengthening the human-canine bond and guiding responsible pet ownership.
