I always like to see studies confirming what we thought we already knew.

Envy is a dog's life, study finds - Yahoo! News:

"Dogs can sniff out unfair situations and show a simple emotion similar to envy or jealousy, Austrian researchers reported on Monday.

Dogs sulked and refused to 'shake' paws if other dogs got treats for tricks and they did not, said Friederike Range, an animal psychologist at the University of Vienna, who led the study into canine emotions.

'It is a more complex feeling or emotion than what we would normally attribute to animals,' said Range.

The study, which was published in the Proceedings of the National Academy of Sciences, also showed dogs licked and scratched themselves and acted stressed when they were denied rewards given to other dogs"
