In general it looks solid.
I think Fly or Overland Flight should make it onto the list - just really useful. I also like invisibility rather than Bull's Strength for higher levels as it doesn't stack with enhancement items on your AC - maybe bull's strength at first, then swap it out for invisibility at 6 or 8 as a free retraining.
For buffing your animal companion, Enlarge Person works because of Share Spells. The reach and bonus to combat maneuvers is nice. Later on Animal Growth is an excellent upgrade that lets animals do surprising amount of damage.
I'm personally not a fan of Hold Person and Hold Monster as they offer a save every round - and I just don't like SoD's. You do get a +1 to their DC's though, so that helps.
 ninja'd! Yup, any spell with a target of "you" can be cast. So Form of the Dragon at high levels is on for animal companions as well.
Thanks for the comments!
I keep thinking not to worry about Flight because of the bloodline abilities, but they won't come online until 15th which makes them next to useless in PFS.
I doubt I'll spend much money on items for my AC apart from getting the nicest Amulet of Mighty fists that I can afford... but I'll look at some of the other options.
Animal Growth is pretty amazing, I've never looked at it before - if I invest in it, should I also use a later spell slot for Summon Monster, with an eye towards using the two together (when summoning animals, of course)? Perhaps with that 6th level spell slot at level 12 that I forgot to include..? Or would that slot be better used for something like Transformation to really pile on the bonuses?
Remember that Kitsune get +1 to Enchantment DC's every four levels due to their Sorcerer FCB in addition to the racial bonus at 1st level. I'm definitely planning on taking advantage of that!
