Animal Friend

Animal Friend is a Fallout and Fallout 3 Perk.

Fallout

 * Requirements: Level 9, IN 5, Outdoorsman 25%
 * Ranks: 1
 * Benefit: Animals will not attack one of their friends, unless the animal is threatened or attacked first. Exactly what an animal is in this world is open to debate.
 * Note: It has been confirmed that rats and radscorpions are classified as animals by this perk, whereas deathclaws are not.

Fallout 3

 * Requirements: Level 10, CH 6
 * Ranks: 2
 * Benefit: At the first rank of this perk, animals simply won’t attack. At the second rank, they will eventually come to your aid in combat, but never against another animal. This perk affects the Dog, Yao Guai, Mole Rat, and Brahmin.
 * To be checked: Will this perk keep a Raider Guard Dog from attacking you?
 * This perk only applies to the animals that are listed in the description, so animals like Radscorpions, Centaurs, and Mirelurks are unaffected.
