In addition to my duties as Queen of the pack, I do some community service. I keep an eye on the street and sidewalk.
I have a table with a large pillow set up by the front window. It is in the office area where I gather my people. They like being near me. I have them do some brushing and combing during slow times on watch.
When a dog comes by, I warn it not to come near. I use my confident "big-dog" voice and they and their people move on.
