Animal Friend

Animal Friend is a Fallout and Fallout 3 Perk.

Fallout
With this perk, Animals will not attack the player, unless the animal is threatened or attacked first.

Deathclaws are not classified as animals for this perk.

Fallout 3
After the player acquires first rank of this perk, animals simply won’t attack. After acquiring the second rank, these creatures will come to the player's aid in combat, but never against another animal. This perk affects only the Dog, Yao Guai, Raider Guard Dog, Mole Rat, and Brahmin; creatures like Radscorpions, Centaurs, Mirelurks, and Deathclaws are unaffected.

The usefulness of this perk outside of role playing is questionable. It can be considered one of the better "standard of living" perks, as not having to deal with such deadly creatures as Yao Guai is quite helpful, as is not being attacked by raider or Talon Company guard dogs. However, the player can, with patience and small effort, build a character up to a point where any Wasteland animal is simply no longer a threat. Furthermore, if the player does not approach too closely, animals will in any case often attack non-animals when encountered.

Additional Dialog

 * With this perk, a dialogue option becomes available when speaking to Tree Father Birch in Oasis. He will then explain why there are no animals in oasis. There appears to be no other benefit.

Bugs

 * If the player removes this perk via the console, animals may behave as if you still have the perk.
 * On the Xbox360 version at least, animals help you in fights even without the second rank of this perk. This has been confirmed when fighting a Mister Gutsy with a Yao Guai nearby.
