As Serum said if a player wants an animal to do something it would have to be Pushed. Without pushing it, it would be friendly towards the sorcerer and by extension it would probably not be hostile to the rest of your group. But it may be potentially unfriendly, such as a dog that bites at anyone other than its owner if stroked. Depending on the animal it may try to groom the sorcerer as its natural friendly greeting response, or something far more inconvenient, such as initiating mating rituals! It might be worth researching/imagining the typical friendly response of the animals likely to be encountered and having them prepared.
Thanks for the advice--I'll definitely do more research to figure out what kind of reaction the various creatures might take once charmed--that will add some fun flavor. For example, a feral chemosit seeking the taste of human flesh, once charmed & friendly towards the caster, might be more difficult to keep away from the rest of the party due to its voracious appetite to kill.
I would argue that unless the creature has the ability to reason and interpret higher level suggestions such as a humanoid would (i.e,. "stay away from my friends"), despite the fact that it would understand the caster's language, its natural instincts would influence how it reacts to the situation. Just because the serpentine bloodline arcana allows you to influence these types of creatures using spells normally geared towards humanoids, that does NOT mean that the affected creatures automatically react to the spell as if they were humanoids with a higher intelligence and can interpret more advanced requests of the caster.
