In 1994, Russian conceptual artist Oleg Kulik posed naked, pretending to be a guard dog, attacking passers by in Moscow.
He was protesting conditions in post-Soviet Russia. He claimed Russians had lost their ability to relate to each other, and were reduced to living like animals.
In this programme, first broadcast in 2014, Dina Newman speaks to Kulik about his protest performance, which made him famous around the world.
