Here's one I was really happy with; I spotted the broken fence walking into the back yard, and thought that if I could get the owner behind there with the pup, with her husband behind me attracting the pup's attention, we could get a great pic with a very shallow depth of field.

This was with a tripod-mounted D200, with a 70-200 lens at about 180mm to compress the features. I had a Speedlight in a small softbox about 45 degrees and above the pup.
