Ha! I knew it!

*dancing around*

I just knew dogs could feel emotions like jealousy and pride, my dog certainly did, and so does every other doggy I know.
But nooooo, my brothers and parents said I was crazy.

Now who's crazy, huh? HUH?! ;)

From England's The Telegraph:

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.
