My sister has two german shepards. One is a retired military service dog and the other they got as a puppy a couple of years ago. The first one is really calm and well behaved and the second is a happy go lucky coward. It's very funny to watch them together.
Most days I walk my dogs I fanatasize about not detouring around small, "vicious" dogs just to see how their idiot owners react.
Did you see what I did there?
