I think there should be a fenced up area at the parks where people can let their dogs off lead where parents should be aware that this area is not for children games...its simply for dogs.

Some people dont have a large garden or dont have a garden at all and dogs need to have a run about....with other dogs as well.
Which when u go along through the woods u dont often meet.

I let mine off the lead in the park but put them back on lead when i see other people coming.

Maybe there should be certain areas where dogs should be on leads, but I don't agree with all public places, because that would just be silly.....
Do you guys realise that a public place is any where outside your own home? So basically your dog has to be on a lead at all times...

I would have one incredibly over-active Jack Russell if that was the case.

I always let my dog off the lead. Because she is well trained and stays within a few feet away at all times.
