Dogs live in a system of heirarchy where one is top dog ... all the time
it sounds like this is what's going on
But lunging and growling isn't a good behavior and should be stopped because it can escalate
When you're on the couch and one does that.... it's AH! and off the couch
Real quick and to the point
Ah! and Off
