During The Lair of Tarn Razorlor, four of these need to be fought alongside some Animated Steel Armour and Tarn Razorlor. After Tarn Razorlor has been slain they are aggressive and will rush players in a Prayer-draining area that can create problems for the unprepared. Terror dogs do not count toward fulfilling a Slayer task for dogs. Their drops are very similar to the drops of green dragons, and are the only monsters that drop granite helms.
