Dogs can be jealous, say scientists

Canines do not like seeing their owners offering affection to other creatures, especially other dogs, and react negatively when their owners bring home new partners, the research found.

Psychologists previously believed most animals lack the "sense of self" needed to experience so-called secondary emotions such as jealousy, embarrassment, empathy or guilt. These emotions are more complex than feelings associated with instant reaction – such as anger, lust or joy.

Dr Friederike Range, of the University of Vienna's neurobiology department, has shown that dogs feel intense jealously when they spot that they are unfairly treated compared with other dogs. "Dogs show a strong aversion to inequity," she said.

The dog study is the latest into several species, including cows, horses, cats and sheep, which have shown that animals are far more self-aware than was thought.

Dr Paul Morris, a psychologist at the University of Portsmouth who studies animal emotions, told The Sunday Times: "We are learning that dogs, horses, and perhaps many other species are far more emotionally complex than we ever realised. They can suffer simple forms of many emotions we once thought only primates could experience."

In research among dog owners, Dr Morris found almost all of them reported jealous behaviour by their pets. The dog often tried to prise their owner away from a new lover in the early days of a relationship.
