Loukanikos hates Greece’s austerity measures, corrupt politicians, and the plight of the Greek everyman. And, as a dedicated protester, he is willing to brave riot police and tear gas for his beliefs. Either that, or Athens’s most famous stray dog just likes the food and the attention afforded him by Greek demonstrators. Whatever the cause for his loyalty, Loukanikos (which translates to “Sausage” in English) has barked and marched alongside protesters since demonstrations in December 2008. This year, he posed for a very stately portrait for TIME.
