Compel Hostility with Animal Companion

[Gevurah]

1. Can I get Compel Hostility to work on my Animal Companion via Share Spells?

Share Spells (Ex) wrote:

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.

2. If so, does the Animal Companion take the immediate action to attempt to redirect the attack towards him or does the caster take the immediate action?

3. Assuming the Animal Companion takes the immediate action to redirect the attack. Do I need to teach the beast to use this spell via Receive Spell?

The companion has been trained to be the recipient of a specific spell (chosen at the time the animal is taught the trick), allowing it to fully take advantage of the spell’s effects. The spell should be one that grants the companion an ability it might not normally be intelligent enough to make use of or one that it might not even realize it has (such as air walk ). The companion is able to recognize when it has been affected by this spell and can take full advantage of the spell’s effects. At the GM’s discretion, a companion can also be trained to receive certain nonspell effects, such as those granted by an elixir of fire breathing. The companion can be taught this trick multiple times; each time it learns this trick, it becomes trained to utilize a different spell effect.

Thanks in advance!

You absolutely can.

And it's on the pet so it's the pets action

And gm discretion. But protect it defend tricks may be good enough to understand.

I'd go with yes, the AC and yes.

The spell has a target of 'You', so is eligible for Share Spells, assuming you've got the spell on your class's list.

Because the AC is the target of the spell, it will need to take the Immediate action

That seems like something an AC wouldn't normally be intelligent enough to do (not sure even an Int 3+ AC would), so you'll need Receive Spell

(Where's Receive Spell from?)

Its a trick, it appears in Ultimate Wilderness.

That explains why I'd not seen it before. Couldn't find it on Archives of Nethys either.
