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. Had giant ants, radroaches, bloatflies and scorpions been included(yes, invertebrates are also animals) this perk would be infinitely more useful, and justify the high Charisma needed to aquire it.

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.
 * While this may or may not be intentional, animals will not betray their factions (e.g. Raider Guard Dog) when the player is being attacked with the second rank of the perk. This extends to a surprising amount of things; for example, the Mole Rats in the RobCo Facility don't normally attack the Radroaches, but with the perk's second rank, they still will not, despite Radroaches not being considered animals. Because of this, and how many animals will attack anything that would be fighting you anyway because they consider them enemies (for example, a Yao Guai engaging a Mister Gutsy), the usefulness of the perk's second rank is questionable.
