An eight year-old Belgium shepherd dog wearing anti-bite protection on its teeth, bites Swiss parliament member Oskar Freysinger (L) of the Swiss People?s Party (SVP) during a presentation at the Hund 2010 dog exhibition in the town of Winterthur north of Zurich February 5, 2010. The anti-bite protection is designed to avoid injuries caused by dog bites. REUTERS/Arnd Wiegmann (SWITZERLAND - Tags: ENVIRONMENT POLITICS)
