Select facilities - why not one that says 'no dogs'?

When searching for a site or CL why don't the Club offer an option filter to search for sites that do not allow dogs? Don't get me wrong, I like dogs and come from a family who are actively involved in both dog rescue and dog charities.

It's some of the dog owners I can't stand.....those that think the rules don't apply to them and therefore they and their dogs are entitled to do as they like.

We have the option of filtering for Adult Only so why not a filter for No Dogs Allowed?
