Evasion (Ex): If an animal companion is subjected to an attack that normally allows a Ref lex save for half damage, it takes no damage if it makes a successful saving throw.

Devotion (Ex): An animal companion gains a +4 morale bonus on Will saves against enchantment spells and effects.

Link (Ex): A druid can handle her animal companion as a free action, or push it as a move action, even if she doesn’t have any ranks in the Handle Animal skill. The druid gains a +4 circumstance bonus on all wild empathy checks and Handle Animal checks made regarding an animal companion.

Share Spells (Ex): The druid may cast a spell with a target of “You” on her animal companion (as a spell with a range of touch) instead of on herself. A druid may cast spells on her animal companion even if the spells normally do not affect creatures of the companion’s type (animal). Spells cast in this way must come from a class that grants an animal companion. This ability does not allow the animal to share abilities that are not spells, even if they function like spells.
