Trakr was a police dog who discovered the last survivor of the September 11 attacks at the World Trade Center in New York. Trakr found signs of life under rubble leading firefighters to rescue a worker who had been trapped for 26 hours. On September 14th Trakr collapsed from chemical and smoke inhalation, burns, and exhaustion. After he was released from hospital he was deemed one of history’s most heroic animals and was later cloned to produce five puppies.
