I have no issue with dogs going to parks where sport is played. The park is for everybody to enjoy not just 22 humans to run around. I have a dog, a very big dog (requires two hands to pick up his dump!) and always clear up after him. I walk him around the park behind my house which although doesn't have sport played on it, does of course have lots of kids playing there so should we be banned from there as well? I very rarely see dog poo left behind but there are plenty of wild animals that will dump where they want like foxes. Fox dump is a lot worse than dog dump so should we ban them as well. Unfortunately there will always be people who feel they above the law but I would feel it's unfair to ban everybody because of a few. Much like banning away fans coming to your club because some have played up in the past not that any decent football club would ever do that!
