The Boys- A problem

Having a small problem with Kenji and Rocky. Seems like Ken has been bugging the heck out of Rock and they got into it last night.  I was washing dishing when I heard a loud yipe. Ran to the living room and there was Kenji in a little corner and Rocky rolled up in a ball on the other.  I reached out to pick up Kenji but he yiped again.  Checked to see if he was hurt but there was nothing.  Went over to Rocky who was trembling in fear of what I would do. Checked him and nothing.  Got to keep an eye on those two.  Looks like they are trying to decide who the pack leader is.  I have news for them, its going to be ME.   I'm not going to tolerate aggressive behavior.  As for Chacha, she's a typical girl in her little world.  That is a good thing.
