Because I was taking a picture of the volleyballers I didn't see this Aussie's look at Benni. All of sudden there was a lunge, a lot of growling back and forth and me jumping up to hang on to Benni. She's a sweetheart but if someone is going to attack they're going to have a fight. Fight averted, but we'll stay away from that dog if we meet again.
When I saw this photo I caught the lowered head and "look".
