The study of 1000 domestic animal owners in the south of England also uncovered examples where jealous dogs acted as 'uninvited chaperones' between couples sharing romantic moments.
The research was done by University of Portsmouth psychologist Dr Paul Morris and colleague Christine Doe, and will be presented at the BA Festival of Science in Norwich, on Thursday 7th September.
It challenges the long-held scientific belief that only humans and chimpanzees are able to experience secondary emotions such as jealousy, guilt, shame and pride.
Dr Morris, who is an animal behaviour expert, said dog owners showed 'remarkable consistency' in reporting jealous behaviour.
He said dogs could feel intense pangs of jealousy and animosity when in a 'love triangle' involving the carer and another person or animal.
'The study set the typical behavioural index of jealousy as pushing between the carer and the third party, and this is what happened more than 80 per cent of the time,' Dr Morris said.
'The significant aspect of these findings is that most academic theorists agree this behaviour is appropriately labelled as jealousy.’
Dr Morris said it was readily accepted in the scientific community that dogs, cats, horses and other non-primate animals experience primary emotions such as anger, anxiety and surprise.
Secondary emotions such as jealousy, pride, embarrassment and shame are considered to be the exclusive domain of humans and perhaps chimpanzees as they have the cognitive capacities required to support the complex range of secondary emotions.
But this thinking, Dr Morris said, might have to be revised.
'The study systematically investigated evidence for a wide range of emotions including jealousy, pride and guilt in a wide range of domestic animals,' he said.
'Our study provided good empirical evidence that has convinced many scientists that dogs at least demonstrate behaviour that is very like human jealousy.
'The data clearly suggest that complex emotions are present in a wider range of species than once thought and that animals do indeed have rich emotional lives.'
Dr Morris has been invited to present his paper 'Proud Horses and Jealous Dogs: Evidence for Secondary Emotions in Non-Primate Species' at the BA Festival of Science.
The Festival will be in Norwich from 2-9 September, bringing over 300 of the UK’s top scientists and engineers to discuss the latest developments in science with the public. In addition to talks and debates at the University of East Anglia, there will be a host of events throughout the city as part of the Science in the City programme.
Dr Morris has delivered the research findings at a recent conference in the United States held by the International Society for Research on Emotions.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
