Judging the age of a dog is not one of my strengths, but I would guess that Dog 163 tends to the older end of the spectrum.

I frequently photograph Dog 163 in his yard. But this week, Dog 163 has been absent and I have to wonder … Here are some of the images of Dog 163, collected over the past few weeks.
