This makes animal friendship totally useless.
The spell descrition states it convinces the animal that you mean no harm. and it fails on INT 4+. So it is especially for beasts like this. And the ability to speak to it should make us able to make clear what we plan to do. The owl bear even realizes that it has something in its eye.
For the situation to be a fight or flight situation, the speech of the owlbear would need to be a lot more primal.
But well, if its game design, what can i say more...
