I have no problem with you not wanting misbehaved children at the dog park...although I have not encountered that at my dog park it sounds like it could be annoying if not dangerous. Sorry its hard for me to relate I have an 11 year old who has already taken veterinary classes at the university here in my town, she will clean up caseys diarreah when I am at work and call me and tell me how her eyes are and how her nose feels. She also volunteers at the spca.
