geez, the kids around here dont act like that. I mean, there are a few that can be obnoxious at times but I have never had one child ever come running up to me and just start grabbing at my dogs. They have always asked first and I always give them permission. My dogs love kids so they love the attention. I agree that the kids need to be taught some manners. I would suggest you talk to the parents and let them know how you feel about it. I also think that letting them pet the dog once in awhile while you are holding him/her wouldnt hurt either, maybe telling them that they need to ask first before just reaching out and touching her. Maybe if you let them pet her once in awhile they may loose the curiosity of it and move on.
