I have three windows along the front of my house. If they're all clean when I return from an outing not much happened while I was gone. If I find that the dining room window has slobber half-way up then someone walked by with a dog on leash. If all three windows have slobber half-way up a cat, deer, or raccoon was in the front garden. If the living room window has slobber three quarters of the way up then Bentley was standing on the sofa barking at the UPS man (or whomever else might have come to the door) pretty much straight in the eye.
Bentley even got me out of bed one night to show me that the garage door had not been put down. My big snuggly panda bear Berner.... Susan Kowitz, Mercedes, and Bentley Sequim, WA
