If your dog "nips" (bites) people, especially children, it doesn't belong at an off-leash dog park. Also, a dog isn't going to die because a child spit hot chocolate on the ground at a park. This busybody should probably spend a little less time ordering people around and educating themselves instead.

Of course I agree that parents should supervise their children inside dog parks. Although I can't take anything you say seriously given your comment that our society bends over backwards to help parents. Maybe you are not aware that the United States does not have paid family leave or subsidized child care or a million other things that would actually reflect giving a shit about parents and kids.

A 21+ dog park?
Aren’t those called bars?
