my little territorial Poodle won the battle.
It's quite funny how size doesn't really tend to be much of a factor as far as "doggie showdowns" are concerned. Here at our shelter there is a Chihuahua that basically runs the place even though he is by far the smallest one here. He kind of terrorizes the other, much bigger dogs so I think there is a lot more to the hierarchy than just who is the most physically capable.
Oh and I agree about the walks. Dogs almost never get tired it seems and it is a great way to stay in shape!
Holy cow, a Chihuahua is the alpha. It's true what you say, no matter the size, there is a kind of attitude that defines the leader or the most territorial.
