Last night Erika, Lola and I, along with Baby, went for a stroll at the riverfront park where we live. Beautiful cool night, etc. Baby was well behaved, not growling or barking at passersby, and in general behaving herself. She did bark once or twice at other dogs, but not bad. Anyway, we were on the bridge and coming towards us was an older man with his hound. Looked fine, but Baby started growling, and 'raised her hackles,' if we hadn't had a good hold of her she would have gone after them I am sure. She has never acted this way before. We went to the car and she was fine the rest of the night. What gives? I have never seen her so defensive, and ready to pounce. Any opinions? A nd yes, I would like to hear them, any of them.
