Peckhamboy - if it's v. runny poo then it's probably foxes. I think it makes more sense to keep the fence (or a prettier version) but make the current dog free area for dogs and leave the path and the rest for everyone else. If dogs are on the path side, then they should be kept on a lead. This means that 1) stupid dogs don't run into the road because the gates have been left open and 2) people who are scared of dogs don't have loose ones running up to them and 3) hopefully poo won't then be a problem on the path (not infallible I realise). I would also suggest that all the gates have a self-closing mechanism since people seem too lazy to shut them (obviously with soundproofing so nearby residents aren't bothered) which will help with dogs/toddlers which I know in an ideal world would be kept under control, but accidents/distractions happen.
