Rules on bite attack, Skinwalker race, question

[EpicFail]

(1)How does Power Attack affect a Skinwalker Rageborn Boar's bite attack? Is it subject to 1.5 times its Power Attack bonus? E.g., if it's at -1 to hit and +2 to damage from PA, does that +2 jump to +3? I'm thinking it's not because it doesn't say under the race description.

(2)For that same character, would the bite be considered piercing, slashing and bludgeoning for DR purposes?

Thanks ahead of time you rules engineers.

It is it's only Natural Attack.

It is a Primary attack, and will deal x1.5 Strength to damage.

Using it alone with Power Attack will net a -1 to +3 to damage.

A Bite deals piercing, slashing and bludgeoning damage.
