Things I May No Longer Do While Playing III: I May Not Iron Heart Surge Rule Zero

Of course not, you need to be Fine at the very least for that.

* If I somehow get a Fine sized character the chihuahua is still not a Riding Dog.
* I can however have a rat.

*A Humming Bird is also a viable option. (Did a Pathfinder Pally with this once. I'd LOVE to do it again in the right game with the right DM. Was a blast to play! )
