>I really do not understand why we think parks should be dog toilets.

"We" don't, but this battle has been going on a long time. The people who passionately argued against dog-free zones and dog parks insisted that there was no reason why 'we can't all just get along and share', when that meant they and their dogs could do whatever they wanted and we had to watch out for both aggressive dogs and where we sat or stepped.

I love dogs, but I've made the choice not to have one because I am not willing to put in the time commitment required for being a responsible owner. Unfortunately this does not seem to stop many, many dog owners.
