If a TITANIC CHAOS KNIGHTS unit from your army has an Aura ability that affects friendly WAR DOG units, while two or more friendly WAR DOG models are within range of that TITANIC CHAOS KNIGHTS unit’s Aura ability, that TITANIC CHAOS KNIGHTS unit is affected by that Aura ability as well.
Example: Two friendly WAR DOG models are within 9” of a KNIGHT DESECRATOR when it is selected to shoot. As a result, the Knight Desecrator’s Taskmaster ability also affects itself, even though it does not have the WAR DOG keyword, so each time that KNIGHT DESECRATOR makes a ranged attack, Hit rolls of 1 are re-rolled.
