How to get Noxious Bite on Animal Companions

[Shorticus]

Is there any reasonable way to do it without resorting to a Drake Companion? After reading another thread discussing eidolons, I REALLY want a giant frog with Noxious Bite somehow. It sounds awesome, to say the least, especially on a Hunter or Mad Dog Barbarian chassis.

The primal companion hunter (which was errated so watch for that) gives a slow progression of evolution points.

At level 9 you'll have enough points and qualify for acid breath weapon. From there you'll have to retrain one of its feats or wait til 11.

That's the best I could find.

I'm not sure that counts though, as it's not a permanent evolution. It's only gained sometimes (I.E. when the Hunter uses that ability).

That's why I didn't jump to that conclusion myself - it's got minute durations and thus isn't permanent and thus I don't think you can take the feat.

The fly spell is sufficient for feats requiring flight. No reason this won't count.
