He walked out of the ex-pen and stood still as I photographed. I particularly liked how this one came out (I digitally removed his leash):

One of his owners stood behind my right shoulder and called out to him while the other owner held up his leash. When I got home I added a little more black to the picture.
I hope JJ is around a long, long while.
