So who is the Boss?

It is so hard to get photos of two little pups when they are on the move. They have been fighting today, but are usually close to me, and when they see the camera they come rushing up to it. But that is NOT what I need. This one was the best I could get. I am finding that Gypsy is the aggressive one - she is really bossy.
Tomorrow, "Brown Boy" or "Hokey Pokey" (as the Other Half calls him) heads off to the North Island.
