5. Takr, the German Shepherd

Next on our list of the most famous dogs in history is Takr, a dog that shows the great things four paws can do. Over 300 search and rescue pups aided their human counterparts in the months that followed the September 11th attacks, helping find survivors from the miles of rubble.

One team was Takr and his police officer handler, James Symington. Both drove from Canada to New York City to help locate imprisoned and no longer breathing people under Ground Zero’s rubble.

They are credited with finding the last survivor, a woman who had been trapped under heavy concrete and steel for more than 24 hours. Their actions earned the skillful Takr the title of one of the most famous dogs in history.

But his fame didn’t stop there. In 2009, he was chosen to be cloned by BioArts International, a company that had been cloning family pets privately for a pretty penny.
