Why doesn't the council have community parks?

We don't have leash laws like in the US, so it is common for dogs to just be allowed to run around in most community parks.

The problem with sighthounds is they will lock on to squirrels, rabbits or other things, and running at 40mph will be out of sight and lost VERY quickly.

So we don't let ours off lead except in controlled places (like this one).
