I could never own dogs that didn't get along. Koko loves every body and all dogs. I have only seen her aggressive once and it was a complete suprise to me then. I had a neighbor with a APBT that came onto my property and came after me. All of a sudden my mild Koko tore into the APBT with a vengence. It left tail between it legs and never came back after that. She wasn't defending her territory she was defending me.

When Kallie (cat)was still with us, we had to keep her separated from Rascal(cat), because Rascal would attack her. She had no defenses because she was both blind and deaf for at least a year before she died. Koko and Rascal are best of friends and to watch them play you would think that Rascal would get injured. So far all of their play is just that, play.
