A dog that sniffed out survivors from under the rubble of New York's World Trade Centre after the 2001 terror strikes is to be cloned.
Trakr, a German shepherd who lives with his owner James Symington in Los Angeles, was picked by BioArts International as the most clone-worthy canine in a competition offering an owner a free chance to replicate their pet.
Symington says he and Trakr were among the first search and rescue teams to arrive at Ground Zero after the September 11 attacks, and were responsible for locating the last human survivor under about nine metres of debris.
