Dog Parks

The other day we went to the dog park, as we usually do every three days.
It was after 7PM when all the dogs come and out sadly...the children.
Toddlers under 5 years old were running around in the big dog section, and I had to put Alice on the leash. (She has a high energy drive for chasing, and she's very hyper) We didn't want her hurting any of the kids since they were running around. I couldn't let Alice run and play because the parents didn't hold their child and the boy could have been knocked over or injured. I MEAN COME ON. It's a DOG park, not a KIDDY park.
Urgh, we contacted the city park laws and the lady rudely said that there was no law against it and if our dog hurt the kids we would be liable.
