The word circulating among news outlets is that a single dog was involved in the Osama bin Laden raid. According to the UK Sun, dogs (typically German Shepherds) involved in Navy SEAL operations are usually strapped with armour and cameras to sniff for explosives, attack armed foes and provide valuable intel for soldiers.
Heavily armoured hounds - equipped with infrared night-sight cameras - have been used in the past by the top-secret unit.
The war dogs wear ballistic body armour that is said to withstand damage from single and double-edged knives, as well as protective gear which shields them from shrapnel and gunfire.
