1) What Would Happen If You Kicked a Chihuahua?
When big creatures hit smaller creatures, it should move them. It should be built right into the size mechanics. Awesome Blow isn't good enough. If a Stone Giant hits a Halfling, that Halfling shouldn't stay in the same square it started in. My house rule is Any creature who hits a creature two or more size categories smaller than itself can initiate a Bull Rush as a free action. Use the Grenade Scatter rules to determine the direction of the Bull Rush.
In addition, what happens when a chihuahua runs right in front of you while you're walking? You trip, super easily if my experience is worth anything. I don't know if smaller creatures should have a penalty to trip at all.
