Not sure if it counts, but it's certainly not fair, you get a much wider range of potential subjects :P
I've got no dog, my favourite one is on the other side of the world (my auntie's 65kg st bernard, 6-year-old puppy).
There's a dedicated dog-park around the corner from me, I was going to try copy Denise's idea and go there with my camera, maybe try take some shots to sell to the owners. But now it's full of earthmoving machinery, not sure what's going on there, but no dogs.
ps, Denise, love the spaniel. Has anyone else seen the movie 'Fluppy Dogs'?
