This concept is DOA then, I'm afraid. Pathfinder 101: don't pick a casting class if you don't envision your character casting spells, especially a primal caster which is the least subtle kind of caster. Unfortunately, you also haven't given any indication of what the character SHOULD be doing in a fight. The implication seems to be they are relying on the raptor to fight for them, in which case summoner is the only real option. Animal companions are not strong enough to carry the proverbial weight of a full PC in combat. Eidolons are, and your spellcasting could be almost entirely focused on buffing it further.
If you're willing to fight alongside your creature, though, you have options. Ranger being the most obvious with innate access to both animal companions and Wild Empathy. However, both abilities can be obtained through the beast master or animal trainer archetypes. The latter actually gets constant speak with animals, which is even stronger. And at that point you can literally play anything, as long as you're actually contributing and not trying to let your pet keep the party alive by itself. (I'd probably avoid casters, since casting is inherently overt in Pathfinder what with the flashy runes and stuff.)
Edit: I suppose Wild Order indicates maybe you want to wild shape into battle forms and fight alongside your raptor? That will be... ok, but you'll still be somewhat weaker than a true martial. I maintain you shouldn't pick a casting class if casting spells on a regular basis breaks the character concept.
Worth noting that you can't turn into a dinosaur until level 7 or 8, anyway. If you want to do combat shapeshicting as your primary thing, your best bet is the animal barbarian again. Reflavor Snake or or one of the other options.
Oh, one problem: barbarian technically can't use concentrate actions while raging, and Command an Animal is a Concentrate action. Your GM would probably handwave that for you, but you should clear it first. There is no balance issue.
