which "they" are you talking about? If the community group then no but if you are talking about the community group getting the council to do something then yes. I would suggest that you dog owners get together to form your own group and start by talking to the "dogs on lead" folks. Its a sad fact that dogs are predators and will chase and kill other animals but as you say, not really fair to tar all dogs with the same brush...if these folk are not dog owners, they may not understand your POV. Are ther other issues? eg uncleaned up mess, noise anything thst people could object to? Do try talking and negotiation, try not to make a fight of it as the council may just decide to take the easy route and ban you!
