It's real. Document it.

A long-running, patient project. The physical resemblances are genuine and recurring. Parks are the best location.

How to shoot it: Parks on weekend mornings, especially near cafes where owners pause, are the richest ground. Shoot at the dog's level with a short telephoto so you can hold owner and dog in one frame, and wait for the pair to align, the matching jowls, the shared expression. Expect to pass fifty dogs for one real resemblance. Ask before shooting close, owners usually love it.

The output: Funny, warm, and surprisingly touching.
