There is a boy in the neighborhood that I do not want my five year old daughter playing with. He is eight and is out of control. The kids in the neighborhood are great except this one boy. He has walked right into my neighbor's house before. Now he has been coming over to my house and playing with my dog without asking. I have a fenced in yard, and my dog loves the nice weather. He has come into the yard and just starts play with the dog. My dog is mostly friendly and has not bitten, but you never know! He also wants to play with my daughter allot. I have told him a number of times not to come into the yard with out asking. I have told his dad my concerns as well. I have been very nice and polite about this. I don't want to be the "mean dad of the neighborhood", but I am losing my patients! What can I do in a nice way to keep this boy from coming around?
