Dog (Fallout 3)

Dogs are animals commonly found in the Capital Wasteland $$

Background
Dogs are described as minimally affected by radiation and quick. An Enclave field research terminal at a small outpost west of the Temple of the Union summarizes Enclave observation and testing of feral dogs in the region.

Gameplay
Dogs are usually encountered in packs of four to six. Vicious dogs (and their variants) are always hostile unless the Lone Wanderer possesses the Animal Friend perk.

Raider guard dog
Raider guard dogs fight alongside their masters, the raiders. Since they are trained as guard dogs, they are very attentive and can spot threats easier than many other creatures. Raider guard dogs will tend to run at targets they find hostile, alerting the raiders of their presence. They are still affected by the Animal Friend perk, but will not attack raiders.

Scavenger's dog
These dogs are found around scavenger's encampments and will be friendly to others as long as they do not act aggressively to them or their master. These dogs have slightly less Hit Points and attack damage than vicious dogs.

There is a Karma loss for killing a scavenger's dog, as well as the scavenger themselves and/or the scavenger's brahmin if they have one. Furthermore, scavenger dogs will attack if the target continues to pursue the scavenger even after a warning is given. Scavengers' dogs will take back items that the thief steals from their master, even if the latter is dead.

Talon Company guard dog
Identical to vicious dogs below, these animals will often accompany Talon Company mercenaries. Much like the raider guard dogs, their Perception is high, and they may spot hostiles faster than the mercs do. They are also affected by the Animal Friend perk, much like their other canine raider brethren, but not attack Talon Company mercs.

Vicious dog
Ruthless survivors of the wastes, these irradiated dogs will always be hostile, unless the traveler has acquired the Animal Friend perk. They are almost always encountered in packs of two to five, usually in open areas. These dogs are dangerous as they can sometimes spawn in semi-random areas. Vicious dogs will often encircle targets in an attempt to stop them from escaping.

Guard dog (Operation: Anchorage)
Used as guards by the Chinese soldiers in the Anchorage Reclamation simulation, these dogs, being simulations, are not affected by the Animal Friend perk, unlike their other canine brethren. Guard dogs are only worth a single point of XP. Just like scavengers' dogs, they share their model with Dogmeat, with the same breed and the same type of heterochromia, while being significantly weaker. Once killed, like all characters in the simulation, they disappear from the game.
