It's good that you can kind of tell what's going on by the type of barking that she does.
Even though Krypto's young, he's already defining his barks. He gives a serious bark for bears, and I imagine that he always will. But, that's okay, as I want to know when a bear is around.
Most people who hear a Rottweiler bark are not going to stop and try to become friends with her.
