Handle Animal against compulsion and charm effects

[Michael Grate]

If my mount is targeted and subsequently fails against one, can I roll my Handle Animal skill to attempt to regain control or would I need a specific feat (Indomitable Mount etc.) to do this or something like this?

If I am able to do this and it is my mount that I am riding, can I use my Ride check instead (similar to the Mounted Combat feat) to try and maintain control?

If these are possible, what would the DC be, the attack roll of the caster?

Dominate animal: There's nothing you can do. Your animal is a meat puppet for the caster. You can hope that you treated it well enough that attacking you is against his character so he gets a new save every round.

Charm animal: Your animal now likes the person who charmed him. It probably won't attack the person who charmed it, even if ordered. It won't attack you even if the person who charmed it tells you to (unless you seriously violated some druids local 704 laws about treating your animal companion) If your mount sees you attacking his new friend he may walk you two apart to cool down or even try to throw you off his back.

The exclusive trick from the animal archive can help it to ignore some commands from charm effects, but probably still won't make the animal attack his new friend.
