I took the girls for a walk tonight, about 8pm. We headed up the street to avoid going by Sadie's house, then walked around the park. On the way back, I chose to go in a way that would have us go by Sadie's house.
When we were about one house away we heard some voices there and then some jingling that might have been dog tags. Fluff stopped, then came back to me and pressed up against my leg while I assessed the situation. We turned and walked a block out of our way rather than risk another altercation. Fluff looked much happier about that choice than she did when she heard the tags.
