Click to play videoNew Delhi: Rescue dogs did an incredible job looking for survivors buried in the debris after the 9/11 attacks.
Two such dogs Ana and Dusty are visiting Ground Zero to commemorate the fifth anniversary of the tragic events.
Six hours after two planes crashed into the Twin Towers on September 11, 2001, firefighters Rick Lee and Rusty Gross, and their rescue dogs Ana and Dusty, were on their way to Ground Zero.
Five years later, standing at the site where they spent sleepless days searching for survivors, the two are still in awe of the tragic loss of life and the heroic feats their canine partners were able to accomplish that human rescue teams couldn't.
Says Rusty, "We basically couldn't keep the dogs on a leash as they would kill us, get caught on something, so basically we let the dogs lead."
Sadly, Ana and Dusty didn't make any recoveries, but they were able to clear the site so that rescue teams could move forward to look for survivors elsewhere.
Both pooches are more than 11 years-old now and will be getting ready for retirement in a short while.
