A dog attacks a British soldier in protective clothing as part of an exercise to keep the dog trained to do its duties at Camp Bastion, a British military base in southern Afghanistan, August 31, 2008. When British troops go on patrol in Afghanistan, they're increasingly taking specialist canine teams along with them, trained to sniff out buried bombs, concealed explosives or suspected Taliban militants hiding in the undergrowth. Since roadside bombs laid under pressure plates have become one of the Taliban's most-favoured and most-lethal weapons, the eager four-legged warriors and their handlers have become an indispensible aid in the grinding seven-year-old conflict.
