Terror dog

Terror dogs are found at the end of Tarn's Lair. Players can access them very quickly by utilising the teleport to Tarn's Lair on the slayer ring, assuming that the player has spent 75 points on a ring or 300 points on unlocking the ability to craft these rings. They are the only monster that drop Granite helmets, making this the only way to get one besides trading with another player or getting them as a drop on a PvP world. They can be killed at level 40 Slayer. Although they are in a multi-combat area, the Dwarf Multicannon cannot be used here. Tarn's Lair quickly drains prayer (much faster than barrows) so it is best to plan on not using prayer. As such, high level armour (perhaps Guthan's) and food is recommended. The spell Bones to Peaches is also useful for food. It is also useful to use a halberd and trap them.

Terror dogs drop blue charms often, about one in every 6-9 kills. Other than that, they appear to have very similar drops to Green Dragons.

Terror dogs do not count toward fulfilling a Slayer task for dogs.

Trivia

 * Terror Dogs were the monstrous dog-like servants of Gozer from the hit movie . They were lion-sized, hairless quadrapeds with glowing red eyes and short, curved horns protruding from the sides of their heads. Although physical beings and not spirits, the terror dogs were nonetheless capable of demonic possession, and although they looked and behaved like nothing more than savage beasts they were actually sentient, intelligent creatures. Notable Terror Dogs included Zuul and Vinz Clortho.
