I think that would be something similar like The PPB FunDog topic..which in time, won't be fun anymore. I don't think it's going to work unless there's an actual prize or recognition. And with being just how good a dog looks in a photo, I don't think I would care to participate.
I think if there was something like being recognized as PBB DOY then there will be more participant.
There are more Dog men on here than photographers.
