Sherman died Wednesday, nearly on the eighth anniversary of the 9/11 attacks on the World Trade Center. With the help of his handler, El Cajon Fire Capt. Steve Swaney, the pair helped look for survivors at Ground Zero for 10 straight days following the attacks.
One of El Cajon's original disaster search dogs, Sherman joined the department in 1997.
“These highly trained search dogs are a valuable and scarce resource to our community; Sherman was an important part of our fire service family and he will be greatly missed,” El Cajon Fire Chief Mike Scott said.
The dog's nickname was Sherman Tank, because he would stop at nothing to find a victim, authorities said.
