An explosive sniffing dog was part of the crack team of US commandos who shot dead Al Qaeda leader Osama bin Laden in Pakistan.
The Sun reported that the dog was strapped to an assault team member who was lowered into the mansion where Osama was hiding in Abbottabad city.
US special forces swooped into Abbottabad May 2 and killed Osama.
It is not the first time dogs have been used for such operations.
These specially trained dogs wear ballistic body armour that can withstand knife attack as well as protective gear which shields them from shrapnel and gunfire, the report said.
The dogs will attack anyone carrying a weapon and play a critical role in raids as they crawl into tunnels or rooms to hunt for enemies.
Cameras are strapped on their heads and these show live pictures to the troops, providing them with critical information.
