Creating a Druid / Rogue Tengu

[SunstonePhoenix]

I've already written up a backstory for this character, but wanted some advice on how she would mechanically. Firstly, I'm thinking of using taking the tengu trait that allows her to have two claw attacks, along with her usual bite attack. Would this mean that with each successful primary attack to a flanked enemy, I would also get the rogue's sneak attack roll? Secondly, I thought that it would be interesting to take a Druid level and take an animal companion, so that the animal companion could be consistently flanking the target of my attacks. I suppose I'm just wondering if this is a wise or unintelligent decision.

Does anyone have any advice as to how many levels of each I should take, if I should even multiclass at all?

Any other miscellaneous advice that anyone might have on playing or creating this character would be much appreciated.

I wouldn't go druid/rogue for this combo. There are so many other classes that would be better.

Replace druid with Cavalier. Take 4 levels of it, then take the Horse Master feat. Now you're set for an animal companion.

Instead of just taking rogue, dip in to a bunch of classes that grant sneak attack to make up for your lost progression. Something like Ninja 5 / Brawler 1 (Snakebite Striker) / Assassin 1
